    Pretty much like Shifty said. So I think no matter what I'd need 76cc heads. How much did they take off the heads to get them down to 67cc? Using performance cams can also make a big difference. It's also the mixture motion and chamber efficiency that get them their reputation for making good power on mild combos.

    Now Ive seen combos over the internet using heads/ stroker with similar cam specs And im finding numbers that are much lower.I run my timing around 34, but im running aluminum heads.

    I have a over with heads, isky h, This engine with heads will be lucky to make hp on a dyno, with no torque.You can choke one of those down pretty easy with a set of heads that are perfectly acceptable on a

    If I went to 64cc chamber heads my compression would skyrocket. So I think no matter what I'd need 76cc heads. Thanks for the dyno test Steve.It's just I got a free good set from a friend.

    So, your saying with the heads, and the HUGE exhaust ports, and the HUGE headers, with pipes and Dyno-Max Bullet mufflers (HIGH flow.Now your computer might blow up because this isn't a chevy, LOL, but maybe you could run this one thru for me?

    They will get good HP and torque on a dyno too. Georgie if your planing on building a SS motor they might not work as well but they will work and win with a.See a pattern here?

    But it's a number big enough you definitely wouldn't need a dyno to feel it. I built plenty of mild performance s with heads over the.I think a bigger performance gain could be seen with gears or a stall before spending the money for another set of heads.

    heads have cc intake runners and would be perfect on a This motor was built and dyno'd by Air Flow Research and produces That's what I have seen many times with combos like the OPs and that swap from a smogger head to a vortec.

    What did heads come on? How much HP does head porting add? How much do Vortec heads flow? What is a Fuelie head? Are L98 heads any good.I know the s are still smoggers at the end of the day but they shouldn't be terrible with the work done to them.

    Can any one tell me how good these heads would be on my single 76mm turbo SBC heads on turbo motor i'll find the dyno sheet.The results obtained using this program should be used as a starting point to determine initial costs and power levels obtained for certain combinations.

    As to heads for afor my money the Dart SS heads have been a better investment than rebuilding most old heads, especially if you want screw in studs and bigger valves.

    Going to vortecs is nice, but the added cost of everthing else does not justify the expense.

    I have an edelbrock high rise intake made just for those heads I have 70 model corvett headers on it underdrive pullies with flex fan electric fuel pump it has to be 9deg adv in order for it to start I have let a lot of people and everyone says it shouldnt stay togeather but the man who built this motor said it has even suprised him I can lay it over to 10, rpms and she will eat the tires off the truck and it has 12bolt with gears peg leg and when I lay in to it it will start with one tire spinning and then go to both spinning everyone who has drove it says it has about hp it will only run on 92 octain with octain buster or valves raddel so now im thinking of putting a stock motor in my 82 chevy short wide body aw yea it has a hyd roller cam and rollers came from comp dont know spec.
