'94 Block into a '99?
 
I asked this over a m.net while this site was having some issues yesterday...

I am looking for a bottom end to build for my '99. I found a block out of an automatic '94 locally. All I'd be keeping is the crank and the block itself. Will this work?

The only think I can think of being different other than the oil feed on the exhaust side is the knock sensor mount. Is this present on the '94?

Thanks

the 94's didnt have knock sensors, i would have to check to see if it has the mounts though
you should not have any problems fitting it though, i know a few people that have used 94-95 blocks and 99+ heads

Yes, it will work and yes, there should be a place to mount the knock sensor (there are multiple good locations for this anyway.)

the only difference should be the lower compression and stronger rods.

Zabac 01-15-2008 10:59 AM

he is not reusing the pistons or rods though

pschmidt 01-15-2008 11:05 AM

Thanks guys. I'm going to go snag this and start to build up a bottom end.

Zabac 01-15-2008 11:09 AM

good luck, i have plans for a build later this year
are you going to keep track of all the parts you had to get, like bearings, gaskets, seals, bolts, etc.
im trying to get everything ahead of time and im sure i will forget something

pschmidt 01-15-2008 11:12 AM

Yeah, I'll inventory everything. Rods I know where to get; how about pistons? I'm looking for something in the first overbore, 9:1 compression ratio flavor.

Braineack 01-15-2008 11:19 AM

weisco. try http://www.importperformanceparts.net/ iirc $439 for 8.8:1 or

http://www.raceeng.com/p-6760-wis-mi...urborings.aspx

they'll most liekly have them in stock.

tip: do not jb-weld your knock sensor on.

TURNS101 01-15-2008 12:23 PM

The 94 block has a spot exactly where the 99 does for the knock sensor. I have done it myself a couple times.

Its an easy transition to that block..

Have fun with it.

pschmidt 01-15-2008 12:51 PM

Thanks for the info on the block and the tip on the knock sensor. I'm trying to avoid all things ghetto on this car, but you never know when they'll make an appearance. :bigtu: I'd at least use the stick welder.

So Wisecos, rods from 949 (this is all if the Chinese stroker crank deal doesn't work out). How about valve train? Raceengineering has some stuff, is there anything better?

Thanks

y8s 01-15-2008 02:14 PM

supertech makes both pistons and the whole valvetrain.

Braineack 01-15-2008 02:19 PM

i wouldn't worry about the valvetrain unless you are thinking of reving higher or throwing in cams.
