Vic Jr or AFR 205's

also, i wouldnt think that geting a 408 over the 400hp mark would be to difficult with either head as long as the set up is right

yah me either but i would like to get my current engine to 400+. The 408 i want 500+. i need to find out about clearence i guess. Correct me if i am wrong isn't there a way to have pistons cut for valve reliefs when they are in the car?

Yea,but its not the best way.....

You can either #1,stuff some rags in there and use a die grinder and a light touch,or #2 you can get a fly cutter that mounts in the head (witch of course means you got to take a couple valves out).

Isky makes the valve cutting tool,and of course you can take it to a mahcine shop and they MAY be able to do it.

how much of a valve relief would i need? they never seem to be all that deep.

Not as much as you would think,sense you got dish.

 

[86bluecobra]

is there a head gasket that could make up the difference?

 

[86bluecobra]

btw i sent you a pm blue

Cometic can be stacked (you add in an extra inner layer) to what ever hieght you need.

And you can also get coppers in pretty thick.

Only you got to watch you dont ruin your quench area,that will cause some detonation.

I'd be more worried about the radial clearance then the deep dish. Nice chatting with you

Thats what I told him to Rick,lol.

Hey,can you PM me your MSN?

i found out i have trw forged pistons from 1987 in my 351w. so i guess i'll call speed pro and ask them about there products from the late 80's top see if they would clear the valves.

 

[86bluecobra]

so far i have found that trw only makes 2 dished pistons a .110 and a .160. a .110 is a -13.2 cc and the .160 i have no idea. now i waiut for afr guys to call to see if either of these 2 pistons will work with the 205.

 

[86bluecobra]

ugg i just found something else out. i am either only running 8.18 compression or at the most 9.06. now to imput new info into desk top dyno and my new hp rating is.......... 351hp with the 9 to 1 and 333 ponies with the 8.2 to 1. ugg now i'm even more disipointed with my car. no wonder i can only run 11's. (LOL)

 

[50ceptor]

i wish i was upset about only running 11s

 

[86bluecobra]

i wish i was upset about only running 11s

i know it pretty pathetic but i guess this is where guys tell you it isn't what the number on the dyno that matters its the number on the time slip and how the car feels.

 

[bluevenom867]

Nice compression for a BLOWER.

 

[86bluecobra]

the guys at probe industries said that my piston will clear the afr 205 no problem.

I think it should,I mean thats a pretty larger dish....

 

[86bluecobra]
