Ok, I've been researching for months, and finally pulled the trigger on some 383 parts. My plan is to get at or near 400 RWHP NA. I'm not a fan of FI setups. My car is a 1994.

What I have bought so far:
Eagle Rotating assembly with cast crank/5.7" I-Beams.
LT1 heads similar to LE2 with 987 springs.
Ported LT1 Intake for 58mm TB

Now the stuff I need to purchase:
Comp cam lifters : CCA-850-16
GM 847 cam
M55A oil pump
SVO 30# Injectors
Comp 1.6 NSA 7/16" Rockers
5/16" guide plates
Comp Chromemoly Pushrods
Comp 7/16" Rocker studs
Taylor 409 wires
NGK TR55 plugs
OEM Timing chain


Does this look good? Any comments/concerns ?
Thanks.

 

You need to figure out your compression? What pistons' cc and head cc?

I have an LE2 head/ cam on my 383 and it spins to 6800. Your 847 will spin above 6k so you'll want a better spring like the comp 918 bee-hives. I already had my springs(987 double springs with titanium retainers) but went with the 918 after talking to Lloyd. If you spin the engine that high you may start collapsing lifters so better get comp r's or Morels. The r's have been getting a bad rap but I have not had any problems with mine. Last time at the track I saw my tach peg and she still runs fine. I may have the OBD1 stall problem but thats another story......

Be sure to buy the GM guideplates, last I knew the comp plates still are not right. Do a search for the part number , I don't remember it off hand. There are many sources on here that are great for info so hopefully more will join in..
