Perplexing question...any help?

Okay, I have the chance to buy either an LT1 vette motor or LT4 vette motor....what are the differences between the two (as in which is better)? Getting all the wiring, ecm, and accessories....could someone please guide me to the best purchase? Thanks in advance!

Car: '89 Formula
Engine: 355
Transmission: 700R4
Axle/Gears: 9 bolt
LT1- 300hp

LT4- 330hp

The other differences are minimal, other than the heads, cam, rockers and a few other minor things, they are the same engine. Id get an LT4 if you plan on leaving it stock, or an LT1 (if its less expensive) if you plan on modifying it.

...Except for the Crane aluminum rockers. Aluminum is for beer cans and airframes, and maybe wheels.
