-Chev sb 6-71 blower & 2 4 barrel carb

Hello fellow Hot Rodders. I have a tech question. Can I install a 6-71 blower with 2-4 barrel carbs on a stock 1964 Chev 283 sc engine, or will the engine be unable to handle the extre stress and breakdown. THX, Marty.

A 6-71 will be too big for that 283. A 142 with a single four barrel carb would be a much better choice. How is the operating condition of the engine? Have you done a compression test on it?

The short answer is yes you can.
Is is a good idea? No
Would I do it? No

But, it all boils down to what you want to do with it. If you plan on running any boost, it will not last long.

If you want it for looks, then under drive the hell out of it and hope for the best.

There area few more steps involved than just bolting it on.
I'm not trying to insult you, just saying.

Chev 283 6-71 blower.

I want to replace the engine in the winter. It snows up here for 6 months!!!! Should I purchase a used sb Chev motor with a 6-71 blower, carb or fuel injection system motor already assembled. May be and ex drag race motor, and save all the work of buiding up my 50 year old, 283 sb. THX, Marty.

Dump the 283 for sure.

I rebuilt one before. What a waste of time.

Thanks for your help, fellow Hot Rodders. I am noy going to spend money on the 283 motor. It is an old and tired motor. You can buy a new complete crate 350 sb for $3,000.00. That will be fine for this 64 Impala. It is a cruiser not drag car. So I am going to keep it as a cruiser, paint it up, and have fun. 4 door sedan Impala's are cool for picking up chicks, and Banging chicks. If I want speed I'll buy a Pro Stock, and put it on the street. Cheers, and No worries. Marty#*!$$$

Ditto! Back in 1970 I ran a '55 Chevy 2dr sdn gasser with a well built, normally aspirated 283 with 1.94 heads and it ran in the 12's consistently. Wound 6500 rpm's, and seemed to want to go even higher. Great motor!

When I was a die-hard Chevy guy the 283 was the engine of choice. Lots of them are still finding their way into traditional styled hot rods for good reason... cheap, easy on gas and reliable. In a light can they go like stink.

That said, I'd buy a good used SBC or a rebuilt rather than spending $3K on a new crate motor. If you're just cursing you'll be $1,500 ahead with a rebuilt.
