[@poortouringhotwiregarage5617]

Had a '72 Nova that had a worn out 307 back in the day. The oil pump gave out on it and trashed the bearings. Didn't have the $$ to fix it right so I honed it out, sanded / polished the biggest groves out of the crank, replaced the rings and bearings, threw in 290° .480 lift cam, camel back heads, HEI, Edelbrock intake and Carter AFB carb and a set of long tube headers I had laying around from another SBC build. Had a 2:76 10 bolt rear end and a TH350. Unfortunately I didn't have the $$ for a higher stall converter so it was a total dog off the line but it would spin to 70 mph in 1st gear! It really was the perfect highway car! Perfect size and got decent gas mileage even though it was loose as a goose. Unfortunately some woman blew a stop sign one icy morning and ended up totaling it out. 😥 Sure do miss that car and need to build another one soon. Prolly won't have 2:76 gears and a 307 this time tho 😆

BEAUTIFUL engine. So, it's NOT a modified 283, but a .020" overbored 350 if I'm understanding(?) My buddy put a nicely rebuilt 350 with the 268 cam and Edelbrock heads into his '56 Olds. My idea was to dress it as an old Corvette motor and refer to it as a "poked & stroked 283". Intake manifold with fill/breather tube in front, vintage 'Vette valve covers, hidden pcv valve in the rear valley area of the intake manifold (like a Pontiac), ram horn exhaust manifolds, louvered Corvette/GTO air cleaner.

Ahhh, the old Carter WCFB. Decent small cfm 4bbl with good primary adjustments. One could actually get fair fuel economy with one. Had a pair on a 325 Dodge hemi. The popular, and easy, thing to do to a 283 back then was to make a 302 out of it by boring oversize. They would run great for a while but tended to break easy. Saw one that broke the crankshaft right behind the #2 main bearing. Engine would still start & idle but made a tremendous amount of noise.

Rocker studs removed themselves at high RPMs, rocker arm instability at high RPMs, rods broke, on those bored to 302 the cylinder walls were weak, factory pistons would crack. There were a lot of aftermarket parts to make them more durable but they were usually out of reach for the average street guy. The one that broke the crankshaft wasn't a very hot engine. It had a factory 4 bbl intake & rochester 4bbl carb. Just a better set of heads & a rebuilt short block. Broke while he was racing it at a local track.

I have a pair of the 4160s and jet plates, I ran them on a dual quad application and they worked well

@@richardholdener1727 On the dyno? Did they have a nice fuel curve? Sometimes the "basic" stuff is the best.

[@wheelbasemedia5814]

Hmmm, with those heads and that big of cam, I would have thought 475 hp all day long.

[@DANTHETUBEMAN]

smaller cylinders are the restriction.

[@jeffjarquin5600]

If you are gonna hot rod a 61 vette I sure would look for streetability out of a 283. I'd just build a 383 and save the original block for a keepsake.

[@joshup1275]

416 hp wow

The DZ 302 is still king of the GM 5 liter engines.

[@carlinshowalter1806]

The real RPM king of stock Camaro motors! crank it up!

[@pmd7771969]

Just do the 302 stroked 400 long rod motor.

Chevy built a 283 stroker that was called a 307 everyone hated them.

[@dennisyoung4631]

Knew someone who had one many years ago. Seemed to go OK for him.

Shrouded bore

Could we see this dynoed with efi?

[@richardholdener1727]

similar results (slightly less power) if you used the same intake and port efi, similar power if you used throttle body efi

What’s a good carburetor for a 383 stroker?

[@richardholdener1727]

what power level

[@youngsoprano222]

About 400hp

Where's the 09 and up 5.7 hemi tests and comparisons

[@pmd7771969]

What you lose in bore is possible to make up in stroke but why not start with a bigger bore block.

[@hotrodray6802]

It's 4 inches

Neither lol
