What will break first

Daves Discount Motors, GP460. 4.2HP totally stock, 8#'s CCW on the left side, pullstart.

$250.00 + shipping

Staton, 3000rpm HD clutch engagement springs. must have, don't bother with this engine without them.

pull starter upgrade from "chevys4me" over at gopednation.com, highly recommended.

good luck,
steve
 
I agree Steve. The 460 motor is decent but I know when they first came out, the chrome plating on the cylinder walls would peel off and the pull starters would last about a week of you were lucky. The pull starter is really recommended. Being stranded because you can't start your motor really sucks. Chris (Chevys) he knows 460 very well and he builds and ports some of the fastest 460s around.

Any other mods that need doing to this engine besides the pull-start & clutch springs...i'm also assuming the chrome plating problem has been fixed?
 
fetor56,

i'm a participant over on gopednation.com where these engines are very common. you can find many posts in the archieves about the poor quality of the cylinder plating from the very start.

over the years, the incidence of failures due to the plating has slowed to a near standstill, though there's no guarantee it couldn't happen.

following a conservative premix ratio with very high quality synth oil seems to be the best insurance. i'm using amsoil saber mixed 65:1, 1.25 turns on both needles.

i changed my base gasket from the stock .020" paper to a .005" copper gasket and picked up noticable midrange torque.

to the point, i'm not aware of anything else this engine needs other than a drive system that can handle it. this engine also prefers atleast 21-22:1 overall gearing on 26" tires.

Detonator:
I won't be ordering the engine immediately cos i'de like to see how 5-7's friction drive turns-out(particularly with Dominator pipe)
In the meantime i'll check out that website for further info.......thanks alot man.
 
the Dom. is not going to be a real factor. it lets the engine rev. further into the rpm range and delivers another couple mph's.

at 15:1 not a chance, 13:1 doubtful, 11:1 slim posibility with lots of sacrificial operating compromizes.

see my thread "biggest engine on friction drive ?" for some good comments and points from experienced friction drive users.
