Well, I've only ever built one 283 and it was in a hyped up rage and a bet right after I blew a engine street racing. After I got my busted motor home the guy I was racing when it blew came by and started running his mouth and P.O.ed me a little more kinda like digging in a open wound and I had an old bone stock 283 in a corner that came out a '63 Impala and I told him I would build that lil baby motor and spank him right now!! He laid $250.00 on the table and told me he'd make me blow another one and take my money. So, I pulled my busted motor, went up in the loft of my shed and got down some old angle milled 461X and a matching Victor Jr. intake. I grabbed a Erson solid roller 278 and lifters out of another box. ( I think the specs were 236/246@.050 on a 108 LSA with .555 lift) I still got it somewhere. And built this motor with a used .018" copper shim head gasket and parts laying around in about an hour and a half it was running in the car. When I backed it onto the road and hit it in front my driveway, I knew what was up. This lil baby motor was pretty bad!! Ol' boy was leading the way and I was hanging back looking for my power band. When we got to the river road, we lined up, and when we took off, I thought I was in trouble. That lil motor let him jump me by a car at least but when it hit 4k RPM, the race was on. I held that lil motor to 7500 and shifted out of fear, not cause it quit pulling. I beat him by 1-1/2 cars and he came up with some lame excuse so he added another 100 bucks to his side and we ran again. I came off the line at 5k and it picked the front wheels up about 8-10 inches and was gone. I beat him by 4-cars that run and he didn't even stop and come back. I got my money from the flagger, me and my boys went back to my house to drink some beer and laugh. I kept that lil baby motor in my car while I was building another one. At the track it ran some mid to high 11s

This is by no way a recommendation for you to set your motor up like this. That was a Monza and a 4-speed with 4.30 gears and a 28" tire. Just before pulling the motor, I ran it to 8200 three passes just to see if it would do it. It acted like I babyed it. Held together with no sweat. With a career best of 11.41 and still running strong, but leaky, I pulled it and put a 383 and a automatic.
