In the process of dropping a chevy 350 in my 1988 jeep cherokee <grin>
It's a 1989 L98 motor (I don't know what it came out of, but I think a camero -- it had tpi, but was removed before I got to it).

Rough estimates on motors from this year put hp/tq at anywhere betweew 190~220hp, and 290~320 tq, in stock trim, depending on the application.

I've installed comp. cams. 4x4 extreme cam (.462:/.480" lift, 262/272 deg. duration), headers, dual exhaust (hi flow cat, 2-chamber flow master exhaust), holly performer high-rise intake manifold, monster 650 cfm carb (ran out of $$$-- going to go with a holyl 4bbl tpi in the future), MSD. Stock heads.

Motor has been completly ripped down, resealed, etc.

It's unlikely I'm going to put this on a dyno.. so, I'm curious, for anyone who has done these mods on this engine.. what can I expect?

 

The stock heads will hold you back without porting n suchsince these heads are in a emissions era. If you are running a carburetor why not just bolt up 400 heads since you have the 4x4 camshaft? Those heads are casted heavier to handle more abuse from the siamesed block design n being in 3/4 ton trucks. I am gona use 400 heads on my 360 build since its just cheap flow n durability. But as for HP im guessin mid 200s at max.
