I have a one-piece rear seal 350 block (1987 and later) and would like to find a 383 stroker kit. Have found lots of kits for the split seal block but having trouble finding a kit for the one-piece seal block. Any suggestions/recommendations. If I cant find a good kit I would be open to buy the individual parts. Any recommendations for a source for a 383 crank only for the one-piece seal block.
Thanks, Jack

Eagle makes them, either as parts or as an assembly. One of their ESP cranks, SIR rods, JE pistons, etc. IRS carries them, check their web page at www.racenet.net or call Eagle in Memphis. If you call Eagle, talk to Bryan, tell him the guy with the silver 83 Z28 with the 400 and the 305 HO air cleaner sent you. He'll probably charge you extra for that.

The BEST 383 kit that I've found comes from Powerhouse out of california!! Their website only has their address, phone number, and email address on it...but at least you'll have a way to contact them!! http://www.enginekits.com
The kit costs $800 BALANCED and you get flat top Pistons (10.3:1 with 64cc), bearings, RODS (don't come with "most" kits you by elsewhere), BRAND NEW 383 stroker crank, BRAND NEW flywheel, BRAND NEW harmonic balancer, and there's more I just can't remember the rest!! You can get the kit with the one piece seal as well!! The entire kit comes with everything you need!! Oh yeah, I was reading a Chevy High Performance magazine and they had an article comparing the balancing work of some of the more "reputable" places and Powerhouse came out on top!! They said the balancing work was so close to perfect that you could basically say it was!! That's where I'm buying my 355 kit from!

I did the Speed-O-Motive kit. I like it very well, and was top notch stuff. But I have heard some bad from the guys on Chevytalk.com about Powerhouses kits. Don't know all the details,just info floating around.
