stroker

A stroker is a 350 Chevy engine with a 400 crank shaft installed. that gives the 350 engine a longer stroke than the original 350. that's how it got the name "stroker". You CAN NOT!! just put a 400 crank shaft into a 350. the block will need to be modified to accept the 400 crank.

That's a very believable HP rating with the right heads, cam, and intake/carb setup. It doesn't even have to be a radical cam to reach that HP rating at the crank with a 383 SBC.
On a sidenote to the "stroker". We've come to think of a stroker as an engine that's stroked to get more cubic inches and torque, but it also can be the reverse with a destroked engine like the 377, or the old 301 (327 with a 283 crank).
Seems most rodders want the lowend torque, longer stroke, and larger cubic inches these days, but it used to be the opposite in the 60's when rodders wanted high revving engines with short strokes.

I love seeing 383 builds. that means more parts for me to build a good combination with those "left over" parts (377ci). I have one that I built with alum heads and moderate cam, in (still mid engine) an 86 Fiero. a true pocket rocket.

Yeah! I bet it is a rocket! What did you have to do to keep it cool?

I don't have access to pics wile here at work, but what I did was fabricate a serpentine belt setup that runs dirrectly on a machined damper. then mounted a pump (from an iron duke) alongside the engine and plumbed into the stock water passages on the front of the block. this gives the needed clearance between engine and frame rail (engine sits sideways ya' know ). custom 3 core rad is in the stock location up front. runs 180* on the hottest summer day in traffic.

Good stuff Russ! Do you have a link to a build thread anywhere? I'd love to see more of this Fiero project!

Thanks BB427,

That car was built 7-8 years ago, so many of the pics are dead links now, but there might be a couple interesting engine shots still active here:
http://www.fiero.nl/forum/Archives/A...-2-086758.html

I still own the car, but don't drive it as much since I got old, and the car got harder to get in and out of.

I was "Russ544" when I lived at the above forum btw.

What I don't know. . is this a common term for what kind of engine? 327 chev? 350 chev? And does it mean the stroke is changed with a new crank, new rods? both? I'm looking at buying (actually been looking at buying for months ) a 32 where the engine is listed as "383 stroker"
It is worth noting that, while GM never installed a SBC 383 engine into a production vehicle, GM does sell (under the GM Performance Parts or "GMPP" banner) a new 383 cid SBC engine. It is based on a 4" standard bore block along w/a 3.8" stroke crankshaft, instead of the traditional 4.030" overbore and 3.75" stroke. This is because they use new blocks, and there's no reason to bore it oversize, so they use a slightly longer stroke crank to get the 'magical' 383 size.

One of the main reasons the SBC 383 is referred to as a 383 stroker, is because Mopar had a 383 cid engine as far back as the late '50s (RB version), and the Mopar 383 B version was a staple in Chrysler products from the early '60s until its demise. A lot of guys got acquainted w/the 383 B engine in the Plymouth Road Runner and Dodge Super Bee in 'the later '60s.

So when the SBC 383 was first created, there needed to be a designation for them that separated them from the Mopar- hence "383 stroker".


Dual 4-barrel 383 D-500 engine w/long ram intake. Old enough to use a generator instead of an alternator.

Funny a buddy of mine and I were just talking about the 377. Him and his dad build tons of these when they were dirt track racing. High revs, as in setting the limiter to 8000! Cheap because everyone would strip the 350 cam and junk them, and junk the 400 blocks after taking the cam. He said literally they built hundreds in a few years. Everyone had a "Gold Racing Engine" he would buy em cheap, build em cheap, and sell them like hot cakes!

I assume you meant "crank" when you said "cam"? Cams wouldn't change much to make any engine a different cubic inch.

I hope you meant the 350 crank in the 400 block, as if you place a 400 crank in a 350 block with stock 5.565 rods you might rev it to 6500 before it throws the rods. The 372 was the high revver small block which was a 400 block with a 350 crank. We used to rev those to 7200 easy.

Hey Cobalt: You forgot about the Mercury 383s (called the M.E.L. engine for Mercury Edsel & Lincoln, like F.E. stood for Ford engine! LOL A few were in the Mercury Marauders. And were sometimes called the Marauder engine!! They were like the 409s with the decks milled off angled to the bore and the piston crown creating the combustion chamber. Just a little trivia for every one! If I didnt work for Ford & Mercury back in the 60s I wouldn't of known that; LOL! That engine has been long forgotten!! But Mercury Performance is still selling the M.E.L. as a crate engine for restorers!

I cant add any thing to the thread its pretty well been covered so I hope every one excuses my little bit of trivia!
