    KEEEEEEEEE-rect. So Actually the 302 isn't a stroker. It's a bore-er. Same stroke, bigger bore. Also known more commonly as a destroker.

    Better questions are -

    1. - Who was the first one to call it a stroker?

    2. - How many times a week can you call yourself a stroker?

    A lot of engine sizes known from one company were actually originally used in another companies cars. Not the same engine but the same displacement. The 327 was originally an AMC Rambler engine. 350 was a Chrysler. The 302 was a Chevy engine in the Z28 a year before ford made one that size. 390? Another AMC engine.

    Guys were building 302 engines back in the late 50s. Called it a 301 around here. Bore a 283 1/8 inch over and cross your fingers and hope it lasts. Put the old Duntov cam in it with a 4;11 gear and hang on.

    Looked in a 1990 Chevy performance parts book and no mention of bearing spacers for the 383 build, very little on the 400 SB either. Back in the day strokers were pretty exotic stuff for the masses.

    Tony Feil engines in Raritan, NJ was doing it in the way early 80's. He did a 427 for me in the very late 70's. 400 .030 over. 400 crank was offset ground on the rod journals to take the early 327 small journal rods (he also used some longer OLDS rods)..a little block clearancing, a couple rod bolts heads got a hit on the grinder, and careful choice of cam and we ran 427 SBC..Req's the 400 flywheel and some extra mallory in the crank counter weight to get it to balance. It was a torque monster up to about 6K. If we only had the quality heads we have today...we were stuck with ported fuelies back then. Modern heads and cams would have easily given us 550HP.

    I know Joe Sherman gets the credit but Zora built a 4 inch bore 3.75 stroke small block for the 1962 Grandsport cars. Add .030 overbore because of using old core and there is your 383. Zora had the luxury of having factory fresh blocks to use.

    327 crank in a 283 = 307.
    and a destroked 400 with a 350 crank and bearing spacers made a 377 with a 030 over bore. I think when the 400 blocks were more common it made sense. jim

    Which 383? 350 block with a 400 stroke crank or a 400 block with a 350 crank? Both produce the exact same torque and hp IF they have the same heads, intake, carb, and exhaust.

    I think Grumpy Jenkins came up with it first. But then again, Speed-O-Motive had them in both configurations way back 35+ years ago.
