350/383/406

Got to plan a build here.

I already have a 350 that parts can be reused like heads and steel crank However, since I already have a 350 block, do I stroke it into a 383? On the other hand, should I just keep the 350 as a backup and start fresh with a 400 block for a 406. Just building a strong street motor, not a track car at all, will be a 4 speed car. Might make it the track a few times a year, just for kicks.

YEs, I know, there is no replacement for displacement too and a BBC is out the question, working with what I have..

Opinions?

67 chevelle malibu / SS/ custom

Currently undergoing a metal work to remove all rust, if I ever get there.

Cant decide on prostreet or cruiser with a 4 speed.

Don't be so sure about the displacement stuff. My pump gas 358 is still quicker and faster than my 461 so far.

Here are some of my results over the years.
Pump gas 358 best of [email protected] [email protected] on a 200 shot.
12 to 1 406 Best of [email protected]
Pump Gas 461 [email protected]

You tell me which one is the best

Not really looking to set the world a blaze with 1/4 ET's....looking for a low 12 to maybe high 11's combo....very streetable, very mild choppy style cam. 450 horse or slightly north...street motor...good torque from idle to 6500 with strong upper rpm horsepower.

Good. 64 CCs. Easy 430 to 450 hp with those heads from a 383. Like the other gentlemen said, what's your goal, what's your cars weight?

Re: 350/383/406

406 would make that goal very easy, and idle fairly smooth, and not need more than 6000 rpm to get it done.
WHT/73 and Binford like this.

More cubes = easier for sure. What's your budget? Horsepower = money as we all know

Re: 350/383/406

Well, the budget is unset as of now...would like to get the motor built for less than 5000 in it.

I vote 383 (you already have the 350 block) with those brodix heads, you're all set for 430 to 450 hp and 440 tq easy. Not opposed to bigger sbc, but you have a budget and parts that lend itself etc.

I tried to be that way....for the money you canít beat it.

Fully rebuilt, with machinework, forged pistons, cam, lifters springs and all the swap stuff for under 4 grand. Easy 500 hp.
