ok guys, get some popcorn... i bought this engine from a guy that had it in his circle track car. it's a 67 400 with 670's and the torker manifold (i think thats what it is, all the stuff has been ground off.) it had been sitting for 6 years in the garage(with new oil, and no rockers or studs, so no strain on the springs.) i bought it, and planned on going through it, putting forged rods and crap, but a week after i bought it, the camshaft eccentric self-destructed on the motor in my car. ok, either pull the motor out, pull the pan, fish out the chunks from the eccentric, or re-gasket the motor in the garage. i pulled the heads off the "new" motor, and everything looked great. no grunge or anything inside, i could still see the hone marks in the cylinder walls. i ordered the good performance felpro gasket set from summit, and i had already ordered the RA4 intake gaskets, as i was going to port the heads, but i had to get the car running. i put all the new gaskets on, and when i got to do the intake, i found that the stock-style gaskets didnt work, and the RA4 gaskets fit better on the head than the others(670 heads, origional torker man.) i just used the RA4 gaskets, put everything together, got it in (that was a nightmare too, motor mount adapters suck) parts i took off my other motor are: carb, took internals out of summit HEI, put in the distributor that came with it, seeing as how the summit one didnt fit, headers, water pump, pulleys, and that's about it. fired it up, and i was chasing a really annoying tapping. pulled the valve covers, did a compression check, and every hole on the driver's side was 45-50 psi. passenger side was 100-125. something was definately wrong, went to adjustible valvetrain, noticed that some of my lifters seemed excessively soft. replaced the lifters, adjusted the valves 1/4 turn past no ticking, and ran with it. it ran much better, and there was a visible difference in how much the rockers were moving. tapping is still there, but it doesnt sound like a rod knock. i really dont care about the noise right now, it runs pretty well, its just annoying, my problem now is getting the thing to idle. i tried changing the step-up springs last night, and whatever i did made a difference, but i don't know whta i had in or what i put in, so tonight i went and bought the assortment, so i know what i'm putting in. that's my project tonight. a friend of mine also suggested drilling an 1/8" hole in the throttle blades so i could get the idle low enough that the idle mixture screws will do some good, what do you guys think. are those enought details?
