    Edlebrock carb dumping gas out the top.....

    I don't think it did any good turning it upside down except to put whatever junk was sitting in the bottom of the bowls all over inside the carb and maybe changing the float levels too. just take the top off and see what is going on.

    fel-pro rear main seal

    mine has the Mancini seal and retainer it started leaking on the break in. I think the fast fish with the stock retainer is what I am going to do. fast fish retainer has no side seals and I don't want to use that one..

    I'm getting close to switching to a roller cam in the big block!

    my solid flat cams with a .904 lifter I run have faster ramps the most roller cams like I said before the solid cam is faster off the seat then a hyd roller nobody can deny that. the weight of a roller lifter will require a little more spring pressure. run what camshaft you prefer but everyone...

    I'm getting close to switching to a roller cam in the big block!

    yes big advantage with cam and lifter wipe out. but no advantage over a solid tight lash fast ramp cam. and a hyd cam flat or roller will lose lift at a high rpms. hyd roller lifters still have the same problems as the hyd flat tappets.

    I'm getting close to switching to a roller cam in the big block!

    so if true on a 500 HP you gain 8 HP minus the HP loss from having to run more valve spring pressure.

    I'm getting close to switching to a roller cam in the big block!

    a tight lash solid lifter cam vs a roller. the only plus for a roller is the lifters can't go flat. I can't see any other advantages for a roller cam but a lot of disadvantages that are mentioned here already go back and look at the posts. I will add one more the roller has a slower ramp off the...

    Budget conscious Performance Upgrades

    try 34 total so just set timing at 10* at idle. it might even be detonating at that much timing. the 474 cam has 232 @ .050 plenty big for low 13's. the torker is hurting low end the rpm performer intake with a bigger cfm carb would be a better combo. 26 inch tire for the strip would help too.

    Running in the trifecta

    the sure grip additive needs to get in there. need to do figure eights in a parking lot to mix it up. the Mopar lube is not as good as the GM and Ford posi lube

    Camshafts: All else being equal, what does an increase in LIFT have on performance?

    Hughes cams are not as fast ramp as comp cams. Hughes cams have a very high lift to duration that is why I shy away from 1.6 rockers. comp cams have a very narrow spread between duration @ .050 and advertise duration more narrow than the Hughes cams. I ran a lot of both cams and Mopar cams over...

    Camshafts: All else being equal, what does an increase in LIFT have on performance?

    yes at a higher rpm you lose lift but at low and mid lift you need to minus the lash off the lift of a solid lifter cam. solid 500 lift minus 15-20 for valve lash = 480 - 485 lift and that is for a tight lash cam.

    383 Rebuild - New Piston Suggestions

    sorry i don't see any pistons. I would want a light weight forged piston with thin ring pistons with valve notches giving me 9.4 - 9.6 compression without decking the block or milling the heads more than .010 just to square it up if needed and a quench of .035 to .050 and running iron heads so...

    Camshafts: All else being equal, what does an increase in LIFT have on performance?

    I would not run 1.6 rockers with a Hughes cam unless you're just going to do 1/4 miles.
