building a motor for my turbo,piston help?

95StangSVT · May 8th, 2008, 05:35 PM

I have the turbo on my car now its got a stock bottom end

but im getting another block done im debating what to do 347 stroker or just a healthy 306? either way i know the piston should be forged dish correct? flat top pistons would raise the compression to much since the heads on the car now have smaller chambers(E7'S),i dont know anyone got a piston and head combo out there for me that there running with a turbo?

i had a -13cc dished head with a 306 bore. i also used a 64cc bowl manowar head. i was able to push damn close to 20 psi on a stock block till it split. i would say use a stock bore and a dished piston. it you dont have the cash for a set of heads egt those gay e7s ported out beyond the 56cc bowl that they come with. check that stock bowl size of the e7 b/c i dont exactly remember what it is

Build the 347. You'll greatly appreciate the extra cylinder volume with forced induction.

347 turbo isnt quite the ideal street motor

im thinking 331 but i dont think a stroked turbo motor is ideal for the street in general,but its not my Daily D just to the track on Wednesdays and out and about at meets on weekends

,what motor do you think i should build for for the street?

331 sounds good

Why is the 347 a bad candidate for a street motor with forced induction? Enlighten me.

well i just proved myself wrong somewhat, even though i ran a 347 for the longest time lol

347 in a daily driver
