    No pics, they're installed.
    Yes they do have the quench pad for closed chamber alum heads.

    When Auto TEC lasered my name on the underside of the piston, they spelled my last name wrong, for some reason it bugged me, like having your name on your headstone miss spelled :confused:

    Is your machinist going to put this motor on dyno would like to see that. You did everything I did in 94 to build my motor, all the best that was available at time. I expect a solid 460hp at 6700rpm 430 ft lbs at 4200.

    The plan was to have it chassis dyno’d by someone he recommends to tune the sniper. Unfortunately I don’t have a car to put it in as of yet but I’m working on it. When I drop off the rest of the parts he needs to complete assembly I’m going to see if he can locate a local engine dyno person that he trusts. As for power I’m hoping for a little closer to 500 hp 450 +/-tq. This motor was built very similar to Mike T Jr.’s and he had 481hp 433tq. With iron heads that are extensively ported. My aluminum heads flow slightly less but Mike made changes to the cam specs that should make up the difference and then some. My machinist had many conversations with Mike Sr. with this build and both are very knowledgeable. Time will tell.

    Well as if my son totaling the car last year the motor was to go in wasn’t enough. My machinist has passed away from a heart attack. Over the past two years we became friends. The knowledge he bestowed upon me will never be forgotten. RIP Rich
    I will sadly be picking up my motor next week and will have to finish it myself or find someone to take on where he left off.

    The short block was complete as far as the rotating assembly goes. As for the rest I hope he had some notes.

    Sorry to hear that:(
    Pretty soon all that will be left are parts changers. The true, talented machinists, craftsmen, and enthusiasts will be gone before we know it.

    Thanks he worked for Cagnazzi Racing. Built engines for Jeg Coughlin, Jason Line and Erica Enders. Was a loyal stand up guy. The amount of knowledge lost in his passing is unmeasurable.

    A lot of tech is going away if we don't capture it and put it on paper. Especially the things you do to make these motors work that may not be standard fare.

    Just started to assemble the motor now that I have a recipient to put it in ( I purchased the Fantom Works car) 01A50493-844E-4837-9273-3B67CA952B13.jpeg and I have a couple of questions. First which side of the back of the block would you put the fitting for a rear oil pressure gauge? I was under the assumption it would be the odd bank side. My machinist put it on the other side. Next question. In the attached picture would there be a benefit of enlarging the holes in the gasket to match the head, or are those just to let air/steam out?

    Sorry I can't help with the oil pressure gauge fitting but you purchased the red 71 with the added N25 bumper?

    I wouldn't fool with a rear Guage myself,...just remember it's 2 to 5lbs lower back there,...if it's 5 at the front you have an issue regardless! On the gaskets no leave it alone

    If you need the rear location I would plumb a hard line up the thru the center of the bellhousing there where the "350" is drill a 3/8 hole and hard line it up to a union up by the intake to make life easier if you pull the engine
