Hey…thanks for reading my post…hopefully someone that knows more than I can help. This motor is in my 86 hatch and was raced for about 6 months before I put it away after getting aggravated and ran out of time to play with my toys.
My father and I built this car and motor over three years of weekends on our backs in the driveway and then just ran out of time and money to play anymore after we kicked some ass on the street!! I miss driving this car and need to get it running right so we can have some time together in it again.
This is the motor and all the specs I have from the receipts from when we built it.
800 CFM Holly Double Pumper Carb
Edelbrock Victor Jr Manifold
Canfield Power Adder Heads, CNC Port Matched 2.08/1.60 and I think the 54cc chambers because I wanted high compression, I think it had 11.7 to 1.
6.550 Trick Flo chromoly push rods
306 Rotating assembly, balanced (306-FT-REG)
5.0 main support system
SLP high volume oil pump
1 ¾” BBK long tubes
Edelbrock timing gear set
MSD 6a distributor, controller box, and coil
Harland sharp roller rockers
Crane Energizer hyd lifters
ARP 7/16 head bolts
Cam Card:
Comp Cams 35-522-8
Grind # FW XE282HR-12 Intake Exhaust
Gross Valve Lift .56 .574
Duration at .006 tappet lift 282 290
Open Close
Valve Timing INT 29 btdc 73 abdc
EXH 77 bbdc 33 atdc
Cam is installed at 108 intake centerline, I degreed it after it wasn’t running right.
INT EXH
Duration at .050 232 240
Lobe Lift .3540 .3600
Lobe Seperation 112
This motor was finished and installed in late 01 before my dad had back problems. This is the same motor DSS ran for 540 horse on the engine dyno and when I ordered it that’s what I asked for.
I thought my running problems were due to the fact that I didnt degree the cam when I put it in so I pulled the motor and degreed it to 108 per the cam card in winter 02. After I put the engine back in I had the same problems listed below and havent really driven it more than 100 miles a year since.
Its running rich, I know the carb is probably too big because it runs rich as a pig, I told my father to order a 650 and somehow he got a 800. The Harland sharps are the loudest rollers I have ever had and need something else, I set them to 0 lash + ¼ turn and that didn’t change anything so I need a recommendation on carb and rockers.
I am getting float at 6000 rpm, is that from the manifold or the lifters collapsing? I know it could be the springs but I don’t know what is on there, they came from DSS that way and I can’t seem to find any specs in the paperwork.
I want to go to a roller tip solid for revs, is that ok with a hyd roller cam to get say…7K out of the motor and should I stay with the same cam?
Is this setup ok for a 150 shot, I don’t want to change over to low comp and use a blower or turbo.
Thanks for your help in advance, I really want to get this up and running right so the old man and I can have some fun when the snow melts (Boston) here.
Once its running right Im attacking the body and paint next...it needs a cage too
Here are some pics....click them
