Hi everyone. My first post here, very impressed with the tech info and attitudes on this forum. I have a tech question for my small block. It's in my E-body but don't boot me because I have a real 71 340 Duster that's getting closer to completion, well, I offered it to my brother and am helping him finish it. I'm in the pursuit of some low-buck power if it's there because there's an SRT4 in town with 25 pounds of boost that I don't want to get spanked by (if it hasn't exploded by the time the snow's gone) .Anyways, I'll list the specs of my engine then ask the question.
73 cuda , full interior
360
stock iron heads (don't know what they are but not magnums)
KB 107's
purple cam part #4452992 (280advertised/ 474lift)
ceramic coated Hedman headers
RPM intake
Demon 750 carb
MSD 6AL
727 with shift kit, stalls at about 2,500
8 3/4 , 3.91
It goes pretty good (mid 13's I'd guess) but I'm thinking it would be worth porting the heads. I've done a bit of porting, with positive results, so, assuming that I do a decent job blending the bowls, valve guide bosses and gasket matching. What kind of hp gains MIGHT I expect? I won't hold anyone to it, I know there're all kinds of variables, I'm just talking an estimate, a range even. It seems to me the heads would be holding this combo back and I would have alot to gain. As a bonus I can do it at work on night shift and get paid for it :o) Trying to confirm that it's worth the effort.
Other tricks up my sleeve to smoke that Neon: (can't believe I even said that sentence, no offence to Neon/srt-4 owners but it doesn't seem right lol) I know I'll kill him off the line and think I can do better yet with traction bars and stickier tires. Will also have sub-frame connectors on by spring. Thanks in advance!
