purring like a (Real Big) kitten...

well finished my header swap and during the inspection found that i had two failed lifters (hense the clatter i was hearing) swapped out the whole set while i was in there no more header leaks or banging against my control arms man it sounds amazing compared to how it did. off to take it for a spin before the rain comes in....have a great day all i know i will....cruise in dinner at the Moose tonight with the local car club...

Hydraulic lifters failed on start up? Hope these last better. Congrats on the headers and hope the cruise in goes well. I've heard about some cheapy chinese lifters floating around that dont' last. Hopefully this will stay fixed and it didn't hurt the cam. Does the pushrod turn on it's own when running, if not then the lifter isn't turning in its bore and it needs to turn to last.

Sounds good.

Is that tach slow? Maybe it's just the vid.

jet i have break in miles on it and i thought it was just the H&S rockers as i heard the were a bit noisy but when i went to prime it could not get oil out of two stems no matter what....tore the top end down and found the lifters collapsed (edelbrock). went up and grabbed the set Mr. P-body recommended as he said there has been a lot of problems with some of the other manufactures in a previous post. so much quieter now....have base set at 8 deg, 35 all in by 2800rpm oil when warm at idle is pegged at 30 and at cruise between 60 and 80. Temp never topped 175 even during a long idle at the gas station. dumped the secondaries from a 15 roll and lit them up jumped sideways hunched down and gripped, then barked second too boot.....WOW!!! at 60 MPH i am at 2000RPM with the 2:56 gear....may just stick with it.

Yeah, I remember, lol.. Cool on the lifters, thought you lost the bottom. Didn't know that was a video, lol.. Sounds great, as Eric said, tach is sleepy, but it revs real quick and bet it is a ball to drive, torque monster. I would keep the 2.56, it's no fun getting 10 MPG with a gear and hear the engine scream at 70.

That sounds real nice Brian. I had to laugh at the camera angle for the rear bumper. Had to make sure we knew eh? LOL.

lol Batman....was just trying to get the sound to come out good on the exhaust the camera mic leaves a lot to be desired, it's a relatively mild cam compared to yours but i have 1:65 rockers which push the lift to around .504 on both ends.

That rear gear sounds nice too. Could I expect the same RPM at 70 mph with the manual using your gear?
