GOOD 6" CONNECTING RODS FOR A 383 SBCBB Biscuit said:This is a street car that I take to car shows, cruise ins and have started taking to the track a few times a year.
The goal is to have a street car with full interior that runs in the 11s at the track. No reason other than bragging rights and a dream.
I have no shortage of projects. So my logic is, if I'm going to go through all the trouble to tear down the current engine to change the cam why not just start fresh with all new known components and stuff this engine in to something else?
I have a 1 pc rear main hydraulic roller 350 that I am going to tear down and have a stroker motor built out of. Here is the question. The motor is a new crate motor with only 2000 miles on it that was pulled under warranty.
My thought is if it has that low of miles do I pay to have it bored .030 over to make it a 383 or do I have the machine shop check everything and if its good leave it a standard bore, hone it and make it a 377?
Will the cost of standard bore stroker pistons be more than the cost to bore since the .030 over is the norm?
The car is a 73 Camaro, 3500lbs with me in it.
Current engine is a .030 350 with L2256 flat top pistons and a mystery hyd flat tappet cam,
ported and polished 461 heads with reworked D shaped exhaust ports 2.02/1.60 valves.
edelbrock Air gap and a 650 DP holley.
I bought the motor complete from a friend when I put the car together. I have changed the heads and intake in the last couple years.
Turbo 350 with a hughes master kit and 3000 converter. 3.73 10 bolt Rear.
The tires I run on the street are 275/60 15
the tires I run at the track are 255/60 15 drag TAs
last time out the car ran 12.80 at 106

if its going to be re-built with a stroker crank assembly
SCAT has some good rotating assemblies

obviously the compression and cam choice should be compatible with that 3000rpm stall and the car weight
I would NOT bore the block UNLESS the bores need to be straitened as the loss of bore wall rigidity is as important as the minimal increase in displacement

on the plus side , when your working with the Chevy v8 engines SBC and BBC, if you select the correct two piece or one piece rear seal components, many aftermarket manufacturers of flex plates and flywheels to reduce manufacturing costs , build a neutral balance flywheel or flexplate and simply bolt on or weld on a weight to allow the same basic part to work with both potential combos
