cam swap
« on: August 01 2016, 12:23:17 PM »
Hello guys! I should get the last of my parts tomorrow. Been educating myself as much as possible on this project. My question is does this sound like a good plan. I was going to put in 6 quarts of Valvoline and one bottle of Lucas engine break-in oil additive with new filter. Cross my fingers that it fires up and runs well, and run it at 2000 RPM's, moving up to 2500 every 5 minuets for a minuet, for 25 minuets. Dump that oil out, put in fresh oil and my usual ZDDP, new filter and drive as usual.

Please let me now if this sounds ok. Also what weight oil would be best for break-in? Was going to use 10W40 but don't know what to use, no place really says???

Thanks again!!!

FT cam? Is it already installed?


If not you could slap some of this on the lobes and bottom of lifters for extra insurance.

My 464 FT cam in my GS was broke in on it and 15/40 break in oil. 20 minutes or so up and down on the rpm a few times. Dropped the oil, installed new oil and filter, then thrashed the shit out of it on the dyno. This was in '07........was out in it Saturday night and she runs like the day it was built.  :)
Good luck shimy!!!

I would run Joe Gibbs break in oil instead of regular oil plus an additive

A lot of broken parts does not make you a racer; it makes you a slow learner.

Found it on Steve's site, seem's pretty straight forward using a volt-meter.

Got it all torn down this morning. Well the previous owner had installed a double roller timing set and new tensioner. The tensioner has about 1/16 inch wear in it. I don't see the point of replacing the timing set, just the tensioner. Thoughts??

I'd run with what's in there. Have you dropped the pan before? Might have a bunch of the old nylon timing sprocket piece restricting flow to the pickup .

I'll get a pic tonight. That's funny, I was on the phone with a reputable vendor today and he told me not to use the tensioner with the double roller chain also. Seems like it was pretty loose without it when I removed them this morning. How can you tell which ones don't need tensioner??

A prime example of why I use a stock style chain and tensioner setup. Of course, it's not cool...and it works mint. Two reasons not to use it, I suppose.

My chain looks like the no tensioner one, the previous owner was using the tensioner. I'll be leaving it off. The shop I was talking to this morning, don't know if we are supposed to name vendors here, so I'll just say Jack said not to use it and that it wouldn't be noisy and I didn't need it with that chain that was in there. Just seems like to much play without it but what do I know  :icon_eyes:

Been reading up on this issue, seems the problem is some double rollers stretched out retarding timing. Seems I dodged a bullet with this one having the tensioner installed and not eating it to the point of destruction. The timing set I got is from comp cams, I would think it would be of pretty good quality so I think I'm going to install it, no tensioner. Anyone have this set installed??
