Ok so i was talking to this guy i now and i told him about how the 86 50 has flat top pistons and that you can not do a bigger cam or heads because the pistons would hit the valves because they do not have valve relief. He told me that i could run TFTW heads and a TF cam and it should not hit The pistons or valves is this so or do i still have to change my pistons to run bigger heads and or cam

ptv has nothing to do with valve lift[&:]..but yes it is a good idea on an 86 to run tfs head as they have canted valves not inline....and cam choices for you are limited to certain ones not because of possible ptv probs but more so cause your speed density

86GT 93LX

a cam affects vacum. speed density reads off of vacum.theres alot of rumors on the 86 motor, ive been thru alot of them.i geuss e7 heads will work on a 86 block. and the e7 has a better flow supposedly compared to the e6 heads. trick flow tw are spendy new. in my opinion you can get your motor redone up nicely with updated pistons for the price of those heads and make the same power.

i am maf i converted it was like the first thing i did i have a 91gt computer i think it is a a9l so do i still have a small cam choices . i just dont want to buy a bunch of stuff for it not to work and then have ptv thats y i was going to get the tf top end kit and i just dont want ptv prob if i get the tf top end kit i just wont to put it on and go no problems you no what i mean guys

mjr46

but the tfe kit with stage 1 cam and make sure you clay the pistons and check clearance ..there is no such thing as bolt on and go without performing proper checks

mjr46

I doubt it...not using stock heads

thanks man like alwas so i should not have any prob with things hitting but just to make shure i should clay the pistons and see if things r hitting and if not then i am as good as gold right

86GT 93LX

well this assuming the engine has been bored out to like a 306 and heads lightly massaged:P but yeah mjr46 i know what u mean

86 5.0L

i probably just pick out a 5.0 out of a latemodel explorer and stuff it in there,

oh if you think your up to the task you can flycut your pistons Isky has a tool for that, seems like it would be a great alternative

ya thats what i was trying to get away from i dont want to have to do that
