    He ordered it at Johnny's Motor Sales Chrysler Plymouth in Hamtramck (been out of business for years). I ordered a 1970 Plymouth Sport Satellite at the same time.

    Appreciate the up date, I looked at your Hamtramck page and certainly trust your info. !!
    First time I ever saw a cutaway of the race engine I'm assuming is the one in your avatar and am curious about the valve angles.
    Any input is greatly appreciated!

    Thanks
    Randy

    Angle between Intake and bore centerline = 33 degrees
    Angle between intake and exhaust valves = 25 degrees
    Intake splay angle = 11 degrees
    Intake cant angle = 4 degrees
    Exhaust splay angle = 8 degrees
    Exhaust cant angle = 0 degrees
    7mm valve stems
    The engine in the avatar is a R5/P7 NASCAR engine we used from 2001 till the R6/P8 version came out.
    The cutaway was done by Joey Arrington for us. Actually, a community college in Martinsville, Virginia did most of the work with parts Joey supplied.

    Sometimes there were police, taxi, government, option books at dealerships with order codes that could be used for unusual combinations. IIRC somebody told me there were 318s with 4-bolt mains on some irrigation pumps. That was about 1971 and the man that told me is long gone.

    Just to add; there were never any 4 bolt main engines ever made by Chrysler for production use. NO truck, industrial, boat, or AAR/TA motors ever had them. It would have required thick webs to be cast into the blocks. And different bearing caps. And special machinery. ---NO WAY --- However, at least one aftermarket manufacturer [Milodon] made 4 bolt bearing caps. They had small angular outer bolts that sometimes broke through the block webs.

    As far as a 340 in a 4-door car, definately possible. Starting with a taxi package type car [hd springs, 8 3/4", hd tranny, cooling, etc.] the 340 would bolt right in. Lots of strange things happen in factories on second shift.

    This brings up a question: if a car is built in Nov. 1970, can it be VIN numbered as a 1970 car if it meets 1970 emissions regs?

    You never know. I have once, around 1978 seen a Dart that had a fender tag that stated it was a 340, but it only had a two bbl carb and look like it was never touch. A older man owned it and he claim he did not change anything. It did look original. I did not craw under the car and check the engine number on the block. I know 340's were only made for HP apps. only, according to the books. My bad, I believe it was a Twister.

    A38 through 1983, AHB from 1984 - present

    The E58 Police 360 kept its "L" code from 1974 - 1980. As a truck engine, it went to "Z" sometime in the 80's, and kept that through 2003.

    I know for sure that the old "HEMI'S" were used for irrigation pumps.

    I doubt it, but maybe it was a 355 race motor that was put in the wagon. Reason I say this is I almost put one in my 72' Van. Put a stock 340 instead.
