6" H-Beam Rods.
Forged flat top JE or Ross Pistons.
.035 File fit Dura Moly rings.
Clevite H Race Bearings.
Lunati Hyd Camshaft special grind.
True double roller timing chain assembly.
Vortech Heads big valves and screw in studs and guide plates.Vortech cast iorn intake for a quadrajet 4 b.The quadrajet 4`s I know a few tricks on.
Dynatech headers triple stage with the muffler incerts.
1.5 and 1.6 steel roller tip Comp rocker arms.Comp 80 wall push rods.
TCI Powerglide automatic.
Money isn`t a problem just want it to be in there with the competition.
Maybe it will be in the competition?
Thanks again Steve.
I would stick with the stock stroke or 3.5" as mentioned above. For a couple CID, you're spending alot of extra money that could be spent elsewhere with more benefit.
I run a 355 with a PG also. Best things to do are get the rotating weight down. We've had 2 motors that were fairly close. LW Keith Black pistons (KB231 w/5.7 rods and KB260 w/6.0 rods), 6" damper, 153T flexplate and a TCI circletrack convertor (PN 741020) If rules allow, a non-functional direct drive convertor is the ticket (9 lbs lighter than the functional convertor that is already like 8-10 lbs lighter than stock). The 6.0 rod motor's rotating assembly is significantly lighter than the 5.7 motor. The 6.0 rods (Eagle SIRs) are 8 grams lighter than stock and the pistons are ~50grams lighter than the 5.7 LWs (which are 50-60 grams lighter than stock pistons) The KB's are relatively cheap too going for under $300 a set.
The 6.0 motor now has almost 2 full seasons on it. It's had a rough life with 2 broken pushrods, 3 broken rockers and bad gas that burnt a hole in 1 piston. 1 new piston, 1 new set of rings and reused bearings and put it back together. That was 25 races ago and it still runs hard as ever. It's actually too much motor for our track and tires. It sees 6500 all the time and has gone to 7200-7400 way more times than I care to count. Especailly on a stock cast crank. (Knocks on wood REAL hard).
I use all Federal Mogul pieces (perf bearings, 1/16" rings, t-chain etc) and a Lunati .534" 245@.050" cam. Although we get to use a Performer intake, 3310 carb and 1 5/8" headers too.
