building a 383

Going to start building a late model 1998 sbc to put in the pontiac. Would like to make it into a 383. Any ideas, books, on the subject?

Here's a couple of links:

I've never built one but I'm thinking about putting one in the the sedan delivery I'm building. I'll probably get a kit and there shouldn't be too much different than building a regular 350...but I haven't checked it out much yet.

I'm sure someone here has built one. I'm interested in info too. The ZZ3 in my pickup has over 50,000 miles of hard miles since its last teardown and its a good candidate.

There are some good 383 crate motors out there too.

383s are a great balance of cubes, stroke and bore for lots of power. They are the best marriage in my opinon and use of the small block today. Yes, the 350 is king of the hill, but the now relatively incremental cost on upgrading to the 383 is driving the kit market up.

There are several kits out there that include every thing you need. I have only used one from Summit Racing for a few.

I do have one suggestion however, because this is a longer stroke crank, I highly recommend complete balancing from stem to stern! It makes a difference in performance and how vibrations get transmitted thru rigid and seamingly unforgiving motor mounts.

Just my two sense!

Just to add to HOTRODJOE do balance it. Have it internally balanced(use a 350 balancer and flywheel) dont use the slinger deal that the kits bolt on to the flwheel flange.(never seen one of those kits yet that did not feel like the motor mounts were solid,unbalanced motor) Also use the 5.7 rod ,it takes a little grinding on the block but well worth it later as the rod angles are not like the short 400 rods(seen some wear pretty quickly,plus you will get a little more piston dwell timeI.E. fill the cyl with the correct cam ) Go talk to a good engine builder not a kit builder as we have been using these motors for years and there are a lot of little tricks to get a good balance. With the prices of engine work(mallory for balancing for one) I would seriously look at a crate motor.Chevy finally builds a slick little 383,we will be testing one we installed this week if it would stop icing around here!!! Its sounds wonderfull though.mike

Went over to my buds today. Picked up a new 383 renagade crank and a set of forged .060 oversized pistons today. Will tear the engine down this week-end and get it ready for the machine shop.
