vin K 350 crate Motor

Vin K 350 for 88-95 chevy trucks.

Is this a plain hydraulic lifter motor? Not roller lifter.

My 92 suburban is pushing 205,000 on original engine.

I want to reuse intake and throttle body and front pulley.

Is there a slight upgrade GM crate motor I should look at? with roller lifters. Gearing on suburban with 700R4 I need a low torque motor. RPMs rarely go over 2500. normal range is 1700-2200 rpm. Thanks

the 88 motor I have has the flat tappet lifters in it. To increase torque I used a 1 inch throttle body spacer. It change the torque a lot at low rpms. It only took about 20 min to install. Bought it on ebay.

you need to either specify the block number here or go to MORTEC.COM,and it will tell you if its either a roller block or alum.inwhich case it is roller.

I believe the truck crate motor will have flat tappets, just like the trucks came with from the factory. Scoggin-Dickey lists a '91-'93 car 350 that I would think had the same roller cam that those cars came with, but their description says it comes with "flat lifters." Part number is 12513151, but I'd check with them and verify what type of cam it has. It's here:
