351 setup questions?!

[CrawlinSlo5.0]

Well fellow stangers i have a few questions for you all. My friend recently bought a block and i have a few questions.

The block has forged eagle pistons, rods & crank. Its alos sleeved. We were told the rotating assembly will handle a pretty big cam.

He has been bitching that he doesent know what heads to run. I told him a decent set of heads that arent to expensive are procomps (super budget build). A guy i worked for owns a machine shop and said i could get a set at his cost and hell do the machine work for close to nothing. (its a deal to not pass up)

I told my buddy and he researched procomps and pitched a fit. Apparently there not good enough to be on his car. so now he wants vicotr jrs or twisted wedge heads. I told him procomp heads are dart castings and edelbrock castings. He says he wants to go with a name brand so whatever.

Heres what he wants to run
a 600 lift cam (no clue which brand or anything)
205 or 208 trick flow aluminum head. he said they flow 300 at 550lift.

would this combo work? or is it going to be a cluster F**k? What would he have to do to make a good combo with this motor. He wants this car to mess everything he encounters up. (Dreamer) Also what do you guys think of procomp? What would be a decent size head to go with for this motor?

Dart and Edelbrock are two different companies, and Procomp is not affiliated with either of them. That being said, Procomp is a name brand, though they're not really very mainstream yet. If he's set on using another brand like Eddy Vic Jr's, or TFS, by all means let him. They have a reputation for being quality parts for a reason. Now if he wants to run some TFS heads, the only ones he's going to find from TFS that flow over 300CFM are going to be High Ports, or the Twisted Wedge Race 225cc heads and a cam at .700 lift. Not very realistic for a street car, IMO.

Does he even have a plan for the car yet? It sounds like a hodgepodge of parts, to me. How does he know he needs .600 lift to meet his expectations? What intake is he going to run? That's not even mentioned yet. I agree with your dreamer comment above. I think he needs to spend a bit of time searching on here, looking at peoples' combos and what kind of power they make.

yeah idk hes really starting to get annoying. he tells me i should research for him. I told him to get lost and do the research himself.

i understand procomp is its own company but the few people ive talked to at shops around here all say that there castings are dart casting and edelbrock vic jr castings. idk i never looked into it much.

He wants to run a 600 lift cam becuase (im guessing) he thinks that its gunna give him more hp. I told him that you need to find a combo that works with everything. I said a 600lift cam is not gunna be ideal for the street. He said " I dont care im going with a 600llift cam and a 2.02 head and thats that" Idk he has his head up his ass.

Im afraid if i ask him waht intake he wants to run its gunna be a meltdown becuase im sure he has no idea.

What do you think would be a good combo for the motor? Apparently a budget build turned into im gunna throw high dollar parts at it.

look into patriot heads. i dont care what know one says ive seen a patriot head right next to an AFR head and they look so close it wasnt funny. and as far as people saying patriot heads are crap and have rough casting they need to spend less time time on the internet.

the patriots ports where very clean and look to be very well made. even the combustion chamber was very close in design to the AFR's. and yes this was real life not what ive read on the internet.

Sounds your "friend" is high maintenance.

 

[90mustangGT]

Does your friend even know anything about what makes engines perform?

 

[CrawlinSlo5.0]

so i take it that the 600lift cam he wants and his 202 heads wont work well. can somone please tell me why. When he asks i can tell him it wont work because......

Im new to this whole engine combo stuff myself. Im starting to read these 2 books i bought on engine building. Hopefully in a few weeks i should have some good knowledge!

 

[90mustangGT]

Its all about matching and eliminating bottlenecks which results in high flow with high velosities.... which equalls high CFM and that makes good performance. It's really, really simple as an engine is a air pump, the more air you can get in there the more fuel you can burn and that makes more power. Then getting that power to the ground and directed into getting the car to move forward is a whole another science he better get a handle on if he ever wants to move.

If he thinks hugh cam and huge heads means huge performance then I predict a huge flop and huge dissapointment as he gets schooled be a car with an engine "half" his size.

 

[BK_CAULEY]

tell him 202 heads dont even exist.

I think means the valve size 2.02. tell that dumbass to go buy a civic and put a 3/4 cam and wing in it.

 

[BK_CAULEY]

yea and get an offenhauser intake with some 50's on the back. lol

Oh quit complaining, is he your friend, or your girl friend you're scared to break up with. If he tells you to do stuff and gets on your nerves tell him to **** off. If I had that much work done on a 351 I wouldnt settle for some procomps. Not that I have the money to even start a build, but I see so many people starting out builds doing it right, spending money on the block, etc, and then just blowing it by wanting to be cheap on the heads, either wanting to put gt40 heads on or procomps, or skimp on other parts. Doesnt make sense. Not trying to defend your friend because he sounds like a tool, but sounds like he wants quality which is what he will get from AFR and TF.

CRAZY QUESTION HERE...

How many cubic inches... this is prime knowledge when chosing a cylinder head

And if he wants high ports... then he should get them, they are probly one of the best cylinder heads for a SBF. Im not gonna get into a pissing match about cam specs, but just cause its .600 lift dosnt mean it wont have street manners. The cam in my 345" motor is around .550 lift, and my e-cam had a rowdier idle. If he is building a big windsor like a 408/427, then i'd consider .600 lift to be small. the cubic inches will make up for the big cam.

If i were building a big windsor id use a TFS R head, and go with a custom tight lash solid roller. Theres plenty of guys using them on the street with great success

 

[CrawlinSlo5.0]

well thanks for the info everyone. Mob he is a friend that is just to lazy to do research on his own. i told him to what he wants and dont bitch when it ****s up or dont turn out the way he expects it too. Its a 351 windsor. So everyone knows. He decided to go with a set of afr's. I cant remember which ones they were. He still wants to go with a 600lift cam. Im not sure what intake he wants to run either. I remember him saying something about a single plane.

I need to do some research of my own. I want to build a motor and need to read up on what aftermarket blocks are a good bang for the buck.

look into patriot heads. i dont care what know one says ive seen a patriot head right next to an AFR head and they look so close it wasnt funny. and as far as people saying patriot heads are crap and have rough casting they need to spend less time time on the internet.

the only patriot heads I have seen have completely screwed up header bolt holes. Looks like someone tried to strip the threads in them before they sent them off.

If its a 357 you could look into the xe282/lunati 51012 with 1.7s . . . its almost .600" lift but since its not he probably won't go for it.

I tuned a 347 (I know not apples to apples) that made 396rwhp with that cam, holley systemax and AFR 205s.
