Crate Engine

Is this supposed to be our engine? If it is, is that a good deal for a new engine that comes with a 70 hp power bump?

Are you talking about the 3.4? if so, no it's not, we are not overhead cam.

Okay, I'll ask....

what do you charge to rebuild a long block? Here's my mild-performance rebuild idea:


Stock 3400 block bored .040" over (1mm overbore)
Stock 3400 crank, but cleaned up a bit
Stock 3400 rods, but lightened and shotpeened, with ARP bolts on the big end
Sealed Power hyperutectic pistons, 1mm oversize w/ matching rings
GM head gaskets for 3500 (94mm bore), ARP head studs
Balance rotating assembly
Stock heads but milled .020", LS1 valve springs, polished exhaust ports
Reground stock cam (lobe lift: .295", duration: 206/210 at .050")
Sealed Power roller lifters, stock pushrods and 1.6:1 roller rockers
Clevite main, rod, and cam bearings

Should provide a healthy bump in performance without busting the bank, dontcha think?

What kind of compression do you want to go with mfuller?

Just a modest bump.....like 10:1.

I'll have to get ya a price quote from the machine shop :)

If you're going to add a more aggressive cam, you REALLY need to port the heads, otherwise the extra lift and duration won't be taken full advantage of. If you already have the heads off to do all this other work, you might as well send them into the shop to have them ported, ya know?
