[Super Chevy]

hi everyone, i haven't posted on here in a while since i got my car on the road. so now i want to build a new engine. im thinking a 283. nobody has them and the everyday person on the street has no idea what it is and would probably think it's slow. 350's are everywhere and now even 383's are everywhere. i know i wont get the best bang for my buck out of it but i think it would be an awesome little engine, I've already got it, and its the casting year with the extremely thick cylinder walls. cant remember the year off hand. so what do you guys think the best recipe for a high revving 283 would be. the car is a 4 speed, and weighs a lil over 3000 lbs.

Well dunno what they say now but the old time recope for those was to use a 327 365HP cam and about a 500 CFM 4bbl and what we used to call fuelie heads which are the 2.02 intakes..That combo was hard to beat back in the day..

283's are hard to make a lot of power out of due to the small bore, a 327 foundation would be a lot better. With that being said we had a 283 on the dyno a month or so ago with 2.02 double hump heads, 9.5:1 compression, 230 duration cam, around .500 lift, high rise Holley dual plane and a 570 Avenger. It made 230 HP. They make nice drivers and can be peppy.

A couple of months ago we had a 408 on the dyno with ported double humps. 240 duration, .600 lift, 10:1 compression, Performer RPM camshaft, Holley DP 750 and it made around 440 HP. It also had a couple inches more vacuum as well. This motor sounds narly and pulls very hard.

Cubic inches simply make it easier to make more power throughout the RPM curve in a naturally aspirated application. That is why, as well as the base level 4" bore, the bigger motors are so popular.

Unless you're taking the 283 out to a 301 or revving it to the moon pocket ported 1.94/1.50 castings are adequate, easier to find and cheaper. Everybody is going to tell you to run Vortec's and while they are a better head they kind of defeat the purpose of building an "old school" motor. Might as well build another 350. This is a motor where the right look and sound is the goal if I read you right. The 30-30 Duntov cam OMT mentioned is a sweet cam for a light 4 speed car and is keeping with the old school flavor. The 327/350HP Hyd. will really make it sound tough as well. Top it off with a 327/350HP Vette aluminum intake or an Edelbrock C4B, C3B or C3BX, a Vette dual point and a set of chromed 283 valve covers and you have yourself a classic 60's Peanut motor.

Back in high school a friend of mine had a 69 Nova with a 283, holley 600, dual plane, headers, unknown solid cam, muncie 4 speed, 3.73 posi. The car was a hell of a lot of fun. 400 and 455 Transams and 5.0 Mustangs were stomped regularly.

Have your rotating assembly balanced. Get your compression ratio to match the cam you'll be using. Use ARP rod bolts.
