383 or 385fast burn in 86 caballero

I have a 86 caballero i got the whole car fixed up and looking good. The only thing left to do is give it a heart. I was thinking of putting in a 383 or a fast burn 385. I am heading towards the 383 but i would like to see what you think. What mods if any do i have to do to get any which one to fit? Thank you in advanced

GM 385 hp 350.....
http://www.gmhorsepower.com/Fast_Burn_385_Base.html
"385 lb.-ft. of torque" (more than 300 lb.-ft. from 1,750 to 5,750)

GM 340 hp 383....
http://www.gmhorsepower.com/HT_383.html
"It produces 435 lb.-ft. of torque at 4000 rpm, but more importantly, it produces more than 400 lb.-ft. of weight-moving torque from 2500 rpm all the way up to its 4000 rpm peak."

Personally, I'd rather have the torque in a truck and the 383 runs on 87 octane junk pump gas.

Either motor will bolt right up using the stock mounting points in the truck. Buy new motor mounts while you're at it.

What I have found works best in determining conformance to emissions laws is to take a ride to the main emissions facility where they do waivers. Here in Phoenix, there are 3 or 4 guys who have offices in modular units behind the facility that you can talk to and try to make sense out of it. Try to seek out those same persons in your area.
