And who's flow bench did you use? Remember there are differences in peoples flowbenches. You may want to consider having a second opinion...
Rick Crawford ported them. No timeslips yet. I have been held back by rain and trans repairs. Hoping for this Sunday.
I dont really have a build yet I'm only 16. But there is a 68 skylark convertible sitting in my backyard that I have been wanting to rebuild and I just got a job so Im looking to start the build (with the help of my dad) soonish. I'll post info on the build when i start. And thank you for the info. I think im going to do what 71skylark3504v and just send the heads to PAE. But will be looking out for those aluminum heads in the far future. I'm sorry I started WWIII aswell.
Keep us posted. Don't be sorry about our disagreements, it allows people to learn new things.:beers2:
For reliability sake, I think only professionals should port heads. Even if you don't see a hole you can still leave areas a little thin and that can cause big problems.
well i'll report back ...if they ever get to TA's shop for grind and shipment this is the only thing thats really holding up my build i dont need all the fancy fuel/rad a/c delete nor blowthrough til i get the turbos in..probably better to break the engine in N/A rather then f/i anyways ha
[quote=flynbuick;1329413]Here is an illustrative example from an actual 1971 Buick 350 build up with porting, larger valves, improved cam, more compression than a stock 71, special intake manifold set up, and shorty headers. The engine dynoed at 350 horsepower and 400 ft lbs of torque. It took $6500 to hire someone to get to that level of performance with good street manners retained. http://www.v8buick.com/showthread.php?t=153248 This referenced build up goes way beyond just porting heads which was the point of reference for the question above. So I am just giving this member some accurate information based on real dyno test results and not estimates or guesses. Also my post above has nothing to do with bashing stock Buick 350 iron heads. Rather I am pointing out that improvements will be made in redesigned aluminum heads such they will perform substantially better than stock iron heads will perform, whether they be ported or unported. Otherwise, there would be no market for these new aluminum 350 heads everyone keeps requesting be made by TA. So based on real test results my comments above are right on the money.[/quote] the monies spent is really no more than any other brand. BUT, we are doing it with 1968 technology. no current supplier is making anything close to what's offered in chevyland, etc. if they made parts like they do for everybody else, it would cause some great concern racing against them. we are doing damn good with what little we have. how many have run a 350 to 7500rpm (nevermind 10k), or a singleplane, or 2'' headers or other wierd stuff i can come up with. and this motor is a test dummy. it's seen issues would make others cringe and still runs great no matter how much we beat it. let's just say there is a acute lack of knowledge out there.

Let me buy you a virtual beer.:beers2:
I was wondering when you'd jump in here, Phil. Seeing what was done with your engine is what keeps me dreaming of a new home for the 2NABOT's old 350. :Brow:
