What is the Max HP on a sealed GM 604

[lowriderglen]

There is a new forged piston for the 604 that will be available from Mahle at the end of this month (Feb). It will not be advertised to the general public and includes a thin ring pack and radial gas porting. It will be lighter and look exactly the same on the top as oem if checked with a bore scope.......thought you might want to know.....

it will be balanced different ,, will stand out if they pull the pan ,, hastings sells a set of rings for them for 60 bucks , instead of the factory ones ,,, they check all of that ,,, if ya get caught cheating ,,, its not pretty ,,,

Looks like a 'crate engine shootout' might be interesting.

No way.
Crate motors = an inexpensive, level playing field.

That is so True!

Hey I see they have the "factory" sealed bolts so the engines must be untouched right? Sure!

How many sets would you like to buy?

[DaveMcLain]

I know I'm going to need at least one set because right now I'm repairing a 604 for a customer. Last year I worked on a couple of those crate engines that had been damaged from over heating or too much hard running.

you can get the seal bolts on ebay and racing junk ,,lol,,, its really a joke ,, i love to be in the pits and hear one come rumpling through ,,, yeah , right ,, that one is legal ,,,,,


you can hear if anything has been done to em ,,, stands out like a sore thumb beside a stock one ,,, i was doing the tech work at a local track ,, they started saying what a great thing this crate engine thing is ,,, how they're all legal , can't mess with 'em ,,, i told them you can get seal bolts on ebay ,,, they're jaw dropped ,,, and ,, it ain't impossible to get them off and put them back on ,,, good idea ,, bad in practice ,, for every good thing ,, somebody will figure it out ,,, its really a built in defense ,,, because who at most local tracks is gonna put up 5000 to protest an engine ?? i've saw it one time ,,,, so the seal bolts keep the cheater in it as much as the legal guy

Four legs is good, two legs is better. Excellent book.
