Ok guys bear with me...if more information is needed then let me know. I am looking for the correct pistons for my set up to give 11:1 compression 10:1 <--- specs from Comp Cam))) at the very least. Here is the list of what I have:
- Comp Cam Magnum Hyd Duration 286 286
- Heads I have 3 pr of heads--2 pr are cast# 3782461 which I think are 62 cc maybe 64cc
- 1 pr are cast # 3890462 which I believe are 63.3cc --all heads are steel
- Alum intake -750 holley
- Rear end 3.73 (haven't checked to make sure yet but if its not it will be )
- and all the norm stuff....ie headers, dual exhaust, etc....
The duration of the cam at .050 is 236 236 <B>
And just to note....this truck when finished will not be a daily driver...it will never tow anything... strictly a street/show truck. I was told I would need some dome pistons unless I wanted to get alum heads and shave them ...which I dont ..money wise that is... Would a forged dome piston with a .125 dome give me enough compression and if not what is the largest dome I can go to without having to buy large domes and having them shaved to fit. Also do you know any sites I can get a set of these pistons for around 400-500 dollars.
Thanks Matt
