New Member Intro

    I want to thank Dusty for coming to look over my Gold Trax, and altho he was not able to fix it, we did find the problem, and I need a new coil for it. I very much enjoyed our time together, he is a true gentleman and very knowledgeable in his field, a pleasant conversationalist, and I consider it an honour to have met him. Thank you Dusty, have a great day, I hope we can meet again.

	I just pulled the heads on the ramcharger, the intake valves left grooves on the pistons, don't know what to do with that either, pulled the cam, and the vendor says they don't have record of my purchase, a likely story.

Was it running? only a few thing come to mind one the valve stems were too long, the cams to high or the cam timing was out, but then it could not have been running.

Could also bee that the wrong pistons were in but then if you did not replace them that cant be the problem another thing that I can think of is over revving the engine and valve bounce. (Springs to soft)

    Thanks Xavier, Nickel, the cam is on it's way back to Melling, its a 4* advance cam, with .050 lift, and I had a 4* advance timing gear and chain, making it 8* advance overall, but 10* or even 20* wouldn't put the intake valves in the pistons, which are the correct pistons, it ran well before I replaced crank and cam, it fired a few times, almost ran once or twice, but never actually ran with the new cam in it. I expect it is the wrong cam, Melling will examine it and let me know, and I'm possibly going to have this block bored .030 over and put 10:1 pistons in it, and I'd love to put a 4 or 5 speed manual trans behind it. The build goes on

    Thanks Xavier, every intake valve put 'cuts' of equal depth in the pistons, and I had 90 psi on 1 through 6, 7 lost all compression after a few revs, and 8 had a constant 50 psi, never seen anything like it, and I've build several of these 360s, and a few 327 and 350 chevy engines. I'll have the heads done local, and the block bored, then rebuild it. It ran like a scalded ape with a crane .459 lift 216 duration cam before I let it sit for 6 years. I had pulled the carb and intake to keep them safe, and that cam got pitted so I got the new Melling with 214 intake, 224 exhaust duration, and .050 lift. I don't race it or run it hard, just normal back country 4 wheeling to get to virgin ground so I want reliability more than performance, but I'm likely to put HHO, avap gas, and evap water systems on it for mileage and power.

Definitely sounds like a cam timing issue , if the pistons are marked the valves will be bent , only takes a few thou and you lose compression , almost seems like the timing slipped a tooth , although porting heads adds power it is very labour intensive which equates to big expense . Good luck getting the issue solved GW , keep us updated ..cheers Mick
