sound like a decent combo, is there a reason you are going after a forged assembley, are you looking to run nitrous, if not you really dont need a forged assembly with this. a nice cast steel assembly would be fine, even hyper pistons, and the pro 1 heads aren't really needed as well you could go with the DART iron eagle Platinum heads, they flow pretty much the same. either way it sounds like a decent combo, i just tend to like to tell people that they dont always have to spend so much money.

oh welcome to the site, there is a great deal of information on here and some really knowlegeable people as well, get us informed on your progress and never feel as if you can't ask us a question.

A deal I couldn't refuse

The component we're bought at 1/2 of worth so that's why we got them; even though they are more than we need like you mentioned; thanks for you honest opinion any ways! John jr.&sr.

well shoot i can't blame you for that, i wouldn't gotten them too, good thing is that if you wanted some extra power you could easly put 150-200 shot on it. not that i really like nitrous. or you could always change the cam and have some machine work on the heads if you want more. you know that it should be able to handle what ever

383 Build.

One thing to check for on a 383 build is rod to cam lobe interference, Some high lift, long duration cams can have interference between the cam lobe and rod when 5.7 or 6.0 rods are used. If this is the case the rod bolt can be chamfered or a small base circle (.900) cam be substituted. To account for deflection there should be at least .050 clearance. It's a Good Thing when they don't touch! Good luck on your build.

plan of completion

The way the build stands is; the short block is completed/balanced; the rest of top end parts are new and will be assembled by a experienced engine builder hopefully; seeing my son and I don't have experience. thanks Johns
