Default main, rod bearings, timing chain set, gasket help....

What is a good set of Main and Rod bearings to go with... oversized at .010"

I see they have 1/2, 3/4, and full groove, different metals....


Whats a good timing set to go with? Cloyse, edelbrock, comp cams - Single, double roller???

Also does anyone know what the compressed thickness of regular Felpro head gaskets are you get in the master seal/gasket kit????

This isn't a race engine but mags. who have done this combo reached around 360hp with 416ft-lbs of toruqe.

Clevite 77 trimetal, full groove if you can put out enough oil volume.

Cloyes Tru-Roller.

Felpro Blue- don't worry about the compressed thickness- it needs to seal, and you don't need anything real fancy.

i'm worried about the compressed thickness so i can see where my compression is... pistons i have net me around 9.7:1 But depending on the thickness and bore of the gasket that can either raise or lower it


oh and i'm also using a stock pummp????

What will knowing your compression tell you? Did you CC the heads? Physically check the deck height??

I have not figured out the actual CC of the heads other than knowing what they are stock. I will check that when i pull the heads apart in a few weeks. I will install the pistons to figure the volume above the piston is.

Good. Stock heads have an incredible amount of variance, even if they have never be resurfaced. Do it correctly, or don't bother at all. The advertised compression of a piston is also usually nowhere near what you end up with, as it is that compression with blueprinted heads.

If you are going through all this trouble, please upgrade the oil pump, and probably the drive, as well. (not too up on AMCs)

OK- sorry I got you confused with the 360/390/401 powered Jeep thread on here.

What is your combo? (Heads/intake/cam/the works)

I ran a McCandless 10:1 short block with a set of Stage II ported X heads and a Hughes 30/38 cam in my Scrambler. It is a fairly old combo, but runs like a raped ape on the street. I will have to find all my paperwork on it to get the specs, I built it over 10 years ago. I do know I ran a Cloyes double roller and a MP high volume oil pump. The mains were full groove C77s or possibly Michigan 77s. I ran Felpro Blues because I couldn't find steel shim gaskets to bump the compression a little.

Pretty sure stock 360s have 1/2 groove mains...

I presonlly like gear to gear timing sets. Thats what i put on my 350 and it sounds cool to. Sounds like it has a supercharger. Its a noicey gear to gear. Wasnt really that much more then a double roller. Its a summit brand one. Nice thing with gear to gear is you never have to worry about the chain breaking or streaching. My .02 cents. A few extra bucks now can save you regrats and head aches in the long run. I already wished i would have done a few things different on my motor.

yeah gear - gear is nice in that you don't have to worry about the chain stretching. But i do not like that loud noise caused by it.

Price a gear drive for a Chrysler some time.

Not a simple job, either, and a double roller should last 100K mi, easy.


I'll get back to you on the engine stuff, plato, remind me if I don't.

If you don't upgrade the pump and intemediate drive, however, just go with half groove main C77 or M77s, trimetal. The headgasket should be fine for what you are doing- I would imagine it to be a Felpro Blue.

Not a whole lot of duration at .050, and doesn't appear to be a fast rate of rise cam. If you have issues with Hughes (I know someone on here did recently), one or two other cam grinders sell FRoR cams that utilize the larger Chrysler lifter- the big cam companies tend to use basic Chevy cam profiles in their MoPar grinds.

You really will need to find out how much work has been done to the heads and find your true compression ratio to get really serious, however.

Well thats the problem. I don't have any flow numbers for the heads... so in all seriousness..... the porting could of hurt them instead of improve them.

For the cam, I was told buy the guy at Chucks Engine Exchange in Livonia that, that was the best cam for my combo. Nice power down low. But i have no idea on this shat.
