You can build a 350 HP 383 or a 525 HP 383. You can build a 383 for $2500 or you can build a 383 for $7500. No replacement for displacement.

63mako, I am rebuilding a 79. I am older...56...400hp is enough and I am keeping the auto trans so wifie can drive it.
I become confused with the abundance of info for these rebuilds. I wish I could go to a website and find out exactly what I need to purchase to rebuild this engine. I am going to have it bored to 30 over. I noticed that bearings are std. Do i need to line bore it? no bearings are spun..crank is smooth. Will new pistons, piston rods....I damaged some...and afr heads get me there?

63mako

I'm 56 also. If your looking at 400 HP, auto, likely 3.55 gear choosing AFR heads will allow you to get to the HP you are looking for and keep great streetability. A Scat cast bottom end will do fine. A mild retro roller is worth it to take full advantage of your heads and never worry about lobe failure. Find a good shop. I would have it checked out, machined and assembled there.
Likely can get by without line bore or decking.
If it was me I would buy an internally balanced Scat rotating assembly.

Get your Quadrajet and distributor rebuilt and setup by Lars.

That would get you the main parts but will need incidentals.

You will have a strong, well matched combo with quality parts throughout and easily 425 HP for about $5000

Unless there is some serious pitting in the cylinder walls, after the first pass or two of the boring bar, the cylinder will look just wonderful.

Thank you 63mako, THAT is what I needed!!!!

This little oops made my mind up....383 Stroker it is!!!!

FS...two owner two piece 350 crankshaft...numbers matching, at least one piece to another!

You'll be happy with a 383 with a roller cam and good heads.

oops!

63mako

Looks like that line bore might be a good idea after all. Center main looks marginal.

I think so also Blue... My older brother was with Aleaska Pipeline back in the day. Home base in Val Dez I think....

63mako, I dropped it from 2 feet, it hit the frame of the engine stand. Karate chop!

But I think you are correct, small expense compared to rebuild of $5k plus...

Yea I'm in Prudhoe bay as we speak. Go home Friday.

There's a lot of heads out the but if you use a really good head you can run a smaller camshaft and hit your target of 425 horse meaning better manners.

oops!

Pretty small cam for a 383 with 3.55 gears.

I looked at it yesterday and liked it.would easily hit 425 horse with good heads. If you went with afr 180s it would have tons of torque and probably make more than 425 horse.

oops!

63mako

Do you realize how much crap these guys would give me on here if I recommended 180 heads on a 383. I'm surprised we haven't heard the 210-single plane argument yet.

63mako, I like your plan...already ordered....

I am doing the body lift this weekend. All of my components are here for the restore of the frame.I am sure there are some items I am missing.
I like to plan ahead on my projects. engine is a year away but I will build it now so it is ready...

bluedawg

The ops goals are 425 horse so if he went 180s he'd have that easy probably more with about 500 foot pounds and could do it with the camshaft you recommended and all done by 5500 rpm using the rpm or rpm air gap. Small ports with a roller cam would yield excellent throttle response as long as his compression was in check with the cam. Would make for a really fun street car awesome manners.

oops!

hereigo

ready for the lift...one body mount left....

hereigo

It's up...

bluedawg

Man oh Man do you have your work cut out for you. I wish I had the ***** to do a frame off, but even if I did, I'm afraid that I wouldn't want to drive it after I got it all nice & pristens.
