Engine rebuild time

RichardM · 04-28-2008, 08:04 PM

The rally car needs a new engine. Can any one direct me to a source that gives the bore and stroke needed to make a 302 in a 347?
TIA
Richard
Whoops, should have put this in the tech section.

Yep! Dallas Mustang took my 4.6 and took it up to a 5.1.

Yep, and my co-driver and wife are still mad at Dallas Mustang because they sold us new suspension pieces for our 1997 Cobra and did not tell us that we needed a few more piece to be able to align the suspension.

4.030 bore x 3.00 stroke = 306
4.030 bore x 3.25 stroke = 331
4.030 bore x 3.40 stroke = 347

Thanks! Now to build one and see how quickly I can blow it up.

I like the 331 as the ring package is in a better
position on the piston than the 347.However there is a 347
setup that puts the rings above the wristpin hole.
I believe its a CHP setup.
