I used More Power Inc. out in Grand Rapids. Just make sure you double and triple check the block once you get it back from the machine shop, and get a good balance job. It sounds like you have a good idea of what you want for the heads. Just make sure your valvetrain is strong as well (NSA rockers, 7/16" studs, chromoly pushrods, etc.) So by all means go and spend the extra on the bottom end

This is the shop I use as well as my neighbor.
I also used this shop when I did Red's 383 and Josh James (yoeasy69) 383.

AWESOME.. love the website might just have to take a trip to grand rapids thanks alot!

Not a problem

[ThreeHonks]

yes you will need guideplates. i recommend the Isky adjustables (which are a pain in the ass) or the basic trickflows. A stud girdle isn't necessary but 7/16" studs definately are. I also recommend Comp Pro Mags or Ultra-Mags over an aluminum body roller rocker. LS7 lifters are a good choice as are Morels.

EDIT: You are planning on a hydraulic roller application right? or else all of that info is useless lol

alright, i am looking at a summit catalog right now i see the ultra gold comp cams roller rockers is that what you are talking about? i see they have a lifetime warranty lol and all i see in summits catalog is the comp cams guideplates? and yes i plan on running a hydraulic roller from Lloyd(custom grind)

[ThreeHonks]

no im talking about the comp pro mags. look at summit online. if you need any valvetrain parts i have a lot of misc. hydraulic roller stuff. rockers, lifters, chromoly pushrods, etc. pm me if anything is wanted.

Have you gotten your cam specs from LE yet? if you dont mind, post the specs, im interested to see in which direction he is going with his new stuff and what LSA he went with for your build.

[JoeliusZ28]

Yup, those are top notch rockers

[ThreeHonks]

thats what you need. But if you want to spend the extra few dollars get the new Ultra-Mags. I have a set of pro mags 1.6 ratio NSA 7/16" stud for sale btw

[kyleozzie]

i know this doesnt have anything to do with my opti well sort of i guess but what kind of plugs are you guys running? i want to buy some good ones lol..

[MunsterZ28]

ac delcos i do believe. no problems after 2 years

[JoeliusZ28]

I run NGK TR6s. TR55s were too hot for my car.

too hot? how do you figure? those are nitrous plugs for the most part

I run tr-55's but gap them at .035" (found this gives me the best results with my setup.

A lof of people also run autolite 103 or 104s IIRC
