  • What flexplate is best with this engine, when its hooked up to a TH350 and B&M 2400 stall convertor? Trans is a TCi, please give me specific brand and part # if possible, Thanks

    Asked by: Vince74
    Flexplate that would be required for this engine is an externally weighted plate for a late model Chevy 350 with a one piece rear main seal.

    I noticed this listing says it comes with a harmonic balancer, does this mean it is not balanced internally or partially? Or is it fully internally balanced and the harmonic balancer is simply over kill? Also does it have roller rockers or flat?

    Asked by: 92CamaroRS
    The crank that is in this engine requires an externally weighted balancer (for a 400 cubic inch) and an externally weighted flywheel for a one piece rear main seal Chevy 350. The rotating assembly and internal parts are balanced and blueprinted to within 2 grams. The balancer is not overkill, it is required to be ran on the engine, if it was not ran the engine would vibrate. This engine is a full roller, roller cam, roller lifters and full roller rockers.

    How much can the compression be increased and still maintain decent reliability? For example could I increase the compression to 10.5:1 or even 11:1, and not have the heads blow off in 20k miles?

    Asked by: 92CamaroRS
    Unfortunately we do not have the option or ability to change the engines final compression ratio here before it would ship from our facility, they are all going to leave here at 10:1

    I currently have a base 350ci engine and I'm concerned about hood clearance

    Asked by: Gene72
    This will fit most applications that came with a small block chevy engine. This would not fit under the hood of most Corvettes.

    Will this engine fit a 1972 Corvette with TH400 automatic transmission, A/C and powersteering?

    Asked by: Gene72
    Yes, the engine will fit, you will need to check the hood clearance of this induction system.

    will this fit a 1997 corvette

    Asked by: jose54
    This engine would not be a stock replacement for your Corvette. We only recommend that this engine be ran naturally aspirated with the carburetor that we supply with this build, and your stock computer and dash will not communicate with this engine. While we do not preform any engine installs here at our facility this setup will be taller than your stock engine and your stock hood will not work with this engine.
