    Bumping this old thread. Nobody was able to identify this camshaft.. I did not use it. Any guesses? :scratch:

    Cylinder head swap

    That valve spring calculation lesson was educational. Thank you :nice: I will run the ported '69 heads as they are. Will try to get a video or sound clip when finished.

    Cylinder head swap

    OK. NEW UPDATE. Found details on the springs I believe are on the built '69 heads. The other engine had Performer RPM cam and intake, and I believe Edelbrock springs to match the cam. Edelbrock Part number 5722 - which is recommended for ALL YEARS. Single spring per valve. 110-120lbs seat...

    Cylinder head swap

    Right.. got that, was just misinformed on the rev limiter. Limiting at 6250 ain't bad, will certainly prevent my engine from lunching itself. Srings. What if I buy replacements that are the same diameter as the current springs?? As long as the retainers and locks match I'm in good shape, no...

    Cylinder head swap

    Can you recommend an more inexpensive valvespring that will work? I've already got retainers and locks.

    Cylinder head swap

    I have a 6AL box and read it would bypass it, looks like that is not so! Rev limiter must be in the ECM. Thanks for clarifying.

    Cylinder head swap

    I'm not too knowledgeable about spring calculations, but they are new springs that came with the E7's. I was told they would work because the X cam has a mild ramp rate and it only needs 110-115 pounds on the seat, where other cams need 130 or so. Though it does provide 135. These 98432 Howards...

    Cylinder head swap

    Makes sense. The last cam was a flat tappet Performer RPM which had max lift of .520, however the springs still supported more cam. New cam is .542, a difference of 22 thousandths, I believe it is pretty darn close. The main springs look identical to the springs I installed on the reconditioned...

    Cylinder head swap

    Whoops, should hit 9.5:1 I don't know why I was thinking it was 10.1 already. It should be bumped half a point. Springs aren't exactly unknown, I just can't remember an exact number. I know they support more than the last cam they were run with, which was a .520

    Cylinder head swap

    They are C9OE 302 heads. Casting number says 302, the first pic I posted shows the casting mark. Tom Monroes book "How to build a small block Ford" incorrectly states these heads as being from a 351. The 302 version is more rare, as far as I know. They are 69, 302, 58cc heads, 1.78 intake/1.45...

    Cylinder head swap

    You're right. I thought I could use them but turns out it was a different part # I'll go ahead and use the '69 heads so I can use the roller rockers, and because it looks like the 69 heads have been ported a little bit. Check it out... how much increase in flow do you think that will yield?

    Cylinder head swap

    I've decided to run the stock E7TE heads. Only change is I will be using the Comp Cams Magnum roller rockers from the '69 heads, part # 1431-16 That way if I sell the car in a year or two I will still have the 69 heads and can have them ported in the future.

    1969 302 heads C9OE "C90E" 58cc chamber Do I go with these heads OR a stock E7TE? '69 heads should bump my compression ratio to 9.5:1 :nice:

    Cylinder head swap

    Swapping heads on my 89. I have two choices for cylinder heads that I already OWN. A fully reconditioned set of E7TE heads I put together with heavy duty valve springs. A used set of ported/polished 1969? 58cc heads with heavy duty valve springs. Which would you choose?? (I cannot afford to...

    tuner suggestions

    What is the total cost of a quarter horse setup?? Why do they charge so much money for the software license, it is very basic software!

    dyno & tune or not?

    What should a decent tune cost?

    I expected that type of response. Let's be honest, who builds a car and doesn't see what it can do. You can't tell if a car responds well to a tune unless you hit full throttle. Good luck to you.

    Hard to believe you're running bald street slicks but have "never hit full throttle". Everyone always talks like their car has been built-up but has never been driven and I see that as a red flag.

    New cam, new rods?

    If you buy a new cam, buy new lifters also.. unless they are practically new. I would also buy new hardened push rods. Don't mess with the bottom end.
