347 stroker...

EscortSportage · May 30th, 2009, 02:36 AM

if you stroke a 302 block to a 347 would u still use the same TF TW heads and intake manny or would you would run a bigger size?

how about cam and TB ?

all that can be reused if it is big enough to support the extra cubes. on my 347 my t/w heads are ported pretty good i have a great flowing intake and a 90mm tb set up.

I wouldnt use them

the intake manny from trickflow has a 75mm opening for the TB so i was gonna put a BBK 75mm TB, and run there twisted wedge CNC built heads, and their matching cam, but now if i stroke it with the extra cubes will it still flow optimum amounts of air etc etc etc or do i need to buy bigger heads and what not

and what do you have to do with the computer after you stroke the engine?

170cc heads??? No, don't use any of them. 302 parts make 302 horsepower no matter what the cubic inch is. You need a bigger runner. Get the fast as cast heads or CNC205 heads Don't use any of the cams. Get a cam ground for your combination.

You just tinker with fuel pressure thats all. Computer wont do anything.

170cc Twisted Wedge heads have alot more power potential than a standard 170cc head like Edelbrock, World, Dart, AFR, ect.. Because the runner is much shorter and the average cross section is larger. The TW use a 4.75" runner length and a standard head uses 5.00" runner length.

Twisted Wedge: 4.75" runner @ 170cc = larger average cross section
Standard head: 5.00" runner @ 170cc = smaller average cross section
