i am putting a budget engine together and i was thinking about using an 86 short bloch(refreshed), with gt40 heads, and tfs stage 1 cam. with a weiand stealth intake and demon 650 cfm carb. what do you guys think good or bad?
also does any know how many thousants= 1cc off of a head?
Do you plan to replace the stock 86t flat tops with notched pistons? If so, it will open you up to more head selections and cam. The flat tops are a source of P2V clearance issues with allot of heads. The TFS heads are one of those exceptions. Good luck with your build!
I would probably be a little concerned with piston to valve clearance with that cam if you are reusing the 86 pistons. Other than that it's probably a good combination and should run nice. What gear are you running?
It will FLY.... the TFS1 cam will be OK but.... always check the p/v when using the flattop no notch 86 heads!!! after the p/v issue is resolved...( advance the TFS1 cam 4* to a better pulse signal to the carb!) run it hard!! and have fun!! cool??
my buddy ran into clearance issues using just e7's and a stock HO cam on an 86 block. It doesn't always work. You're gonna clay for sure. I'll tell you right now, that clearance is close to 0 with e7's, imo, I don't think you stand a chance. Swap out the pistons, or have the ones in that block notched for valve reliefs.
i am gonna tyr to use the 86 pistons. one of my buddies had a 86 with e7's and stock cam and it ran damn good. yes i am gonna clay the motor first. and i have 3.55 gears. i hope it work if so i know it will run good ill keep yo updated.
