max boost on pump gas? - Page 3

I wouldn't do that on AFR heads. They come out of the box ported.

AND they recommend to NOT gasket match or at least my 165's did

what about porting/polishing and gasket matching the upper lower intake?

Gasket match where you can...it makes power.

Keep in mind I have the flat-top pistons and some sweet Eagle H-beams for a 347. Plus I can get you the rest of a stroker-kit too.

do you guys suggest any other mods to meet that bump, or any estimates of HP if you think i'll be higher, because 400rw is just my goal i wouldnt mind making more

also any suggestions on ways to improve low end torque(besides a final drive change) becuase even if i dont make my HP goal torque is what is really gonna matter to me, any ideas on what a combo like this would make torque wise?

a 347 will have plenty of torque down low

Running a 306 with a KenneBell Blowzilla with 10# pulley and see 8# boost with 91 Octane. I think this about all you can push it on 91 Octane. 485 HP FW according to flow numbers datalogged. Have major problems hooking up with Nitto 275/40R17 drag radials, really have to feather the throttle :-)

YMMV, Don

see the only reason i will run N/A is becuase i dont have the money to do the blower applicationi love watching the boost guage, hearing it whine, and the challange of hooking it up in my cobra but i am not willing to sell her to fund the 347 build

Yeah the 347 will make plenty of low end grunt. That's the main advantage of bigger displacement.
