Re: Building an LT-4 383 Stroker from an LT-1
I don't know what the LT means in the designations but are you just building a 383 from a crate motor ? The only thing I see first off is the newer blocks have the spider plate retainer bar that locks the GM roller lifter in position. This is an inexpensive way to start . All you have to do is get a cam to match your combo. As for piston, you need to determine what application you want to run, street , race , etc. As for heads, I think you need to stay between the 195 cc - 210 range, depending on your piston and application of this motor. I have the 195's on my mule 355 and they will be ported and put on a street 383. I do intend to run my current XR 282 retro roller as I don't have a late model block . I do believe you need to stay in the 10 scr or slightly under such as 9.9-9.5 range to run pump prem fuel. There is a bunch of stroker kits out there, you just have to make your mind up on which one. You prolly have visited AFR's site and get flow numbers off the LT 4 heads. I dont think they vary much from the 195 ported.
