Nice Pontiac. I have a 1968 Firebird. I am hunting for a TH400 to build. I have a Kauffman headed 474 (4.221X4.250) comp solid roller, Edelbrock Victor. Makes just shy of 700 HP 643 'lbs of torque. I've had the block since 1989. Long live Pontiacs 😊
@@AEtrane I reduced them to 2.120" intake and 1.700" exhaust. I also notched the cylinder bores to accommodate the valves past .600" valve lift. No issues yet, it runs hard, although I have no clean track numbers or dyno numbers to prove it, as the car has had various issues since installing the motor.
Much love for the 1st gen birds!
Thanks!
Those Poncho 350 are solid motors, good video on your 67 Bird!
Thank you! Yes, lots of fun coming up with it....stay tuned!
You need a 433 gear to launch hard it's been a Pontiac gear for the longest time ever
@@phillipbroady1181 I'd love to run a 3.73 in it, not much more than that so I could keep it street friendly.

That'll be sweet!!!! Thanks man!!!
How you like the 3.08s ? i got a th350 wit 373 gears, Im contemplating changing between 3.08 or 3.23
They are a good all around gear for street and some performance
Are you just running the big valves on it? I've always read that valve shrouding and piston to valve clearance are big concerns, you have any issues?
