Nice looking parts for sure!

I'm more comfortable with the shorter stroker cranks, too. 3.75 or 3.91 is the longest I'd like to go with this numbers matching block. I know a lot of people say I should just pull it and find a 400 or 440 block, but for me that's not the plan. Maybe I'll just put pistons in it and run...

Thanks for the info, I think at this point I'm either going to have to go headers or switch cams because I'd rather keep the stroke reasonably on the small side, just personal preference.

Thanks for the link, I had read that several years back but still a good reread and I've got it bookmarked now.

One of my former clients, FIS in Little Rock, is a great company. Folks seemed reasonably happy to be there. Not a sweat shop at all which is a concern now days.

My mother bought the exact same car at Lenox Dodge in Atlanta in 1969 except hers was a beautiful bronze gold color. I still have the 70 Roadrunner I bought used in 74 but it's been sitting so long not sure what it's going to take to get it running at this point. We lived around Atlanta until...

10 degree lobe separation on the cam, appreciate the advice on the cam. Would be willing to buy more cam if I went with the 4.25 stroke. Thanks

That's awesome, would be very happy with numbers even close to yours!

And that's why I know I don't need to go Hog Wild with the 383 and am looking at a Middle Of The Road path. Doesn't have to be the top HP/TQ, just hoping for a little more than stock while keeping the main parts of the motor together with the rest of the car.

That's kind of what I'm thinking as well, Thanks.

When you say pull gear out of it, go with a 3.23 or 3.55 rear? Wouldn't necessarily need the O/D with those ratios. Thx

Agreed, but only thing I was wondering about is that with the restrictions on air flow will the motor be 'choking' more with the bigger cubes?

It is a Hydraulic roller, already bought it for a higher HP build which may still be the way I go since I already have all the 'matched' parts except the stroker kit itself. Would still have to decide between 432 and 489 c.i, but leaning heavily toward no more than the 3.75 stroke if I don't...

Has original 383 motor so that's part of the decision process. 440Source makes two kits for 383's, a 3.75 and a 4.25 stroker. More than a little concerned about the longer stroke, but their pistons on the 3.75 stroke won't work with the stock 88 cc heads, not enough compression.

Thank you, although I'm barely on FB I will do that.

First off, I've kind of asked this question in other threads but wanted to try again to get anyone's experience actually building such a motor: 383, either massaged 906 or CNC'd Stealth heads, roller Lunati cam, 231/239 @ .50 535/550 lift, either 3.75 or 4.25 crank for 432 or 489 c.i., stock HP...

I've always thought the 70 RR tips gave the car a distinctive growl, there's lots of good videos where you can listen but here's my favorite:

I used to live just south of you in Pike County, rode my dirt bike all over Williamson and later rode my Harleys down through Williamson heading south away from Atlanta. Still have a good friend that lives there. Very cool. Welcome aboard!

I bought a set of brackets from Glen-ray to mount a 26" on a 22" core support, not cheap but beautifully made: Glen-ray Radiators - All New Licensed Mopar Chrysler Dodge Plymouth Radiators doesn't increase the opening, but they said that wasn't a big deal given the 26" radiator provides extra...
