Have real nice 69 RR, 383, 4 speed. No fender tag, not numbers matching. Would like to add some 'gidde-up' with either a crate hemi, (no not a REAL 426), or built 440....but not sure which would be better to re-sell the car?
Im looking at crate 392's plug and play for $6k?Hemi would be nice but I dont think it will return the additional $20k you would spend for it.
I think the 383/4 speed combo gives you the best chance even though it's not a numbers matching car. ..
Why is that? Wouldnt 8 3/4 rear and 833 4 speed handle it?I'm debating doing the same only I'm thinking a differential upgrade and Trans upgrade is going to be necessary.
You could b right my friend!Thsts a big difference, thought you were refering to a 572...I still think keeping the car as close to original will being the most return...

I have a 23 spline trans and 8 3/4 I don't think they are rated for 600hpWhy is that? Wouldnt 8 3/4 rear and 833 4 speed handle it?
It’s a small cube, 3.38 stroke crank engine in a big car. It’s gonna be a pig unless it’s built to be turned 8500rpm and you’ve got 488 gears to get it to move which would be a horrible street combo.I dont get---- getting 400-450 hp out of a 383? It does have Edelbrock aluminum intake with 850 Demon carb.... illegedly rebuilt witha cam about 1000 miles ago, and i think its a pig.... mind you my last ride wax a 31 ford with a 383 stroker small block that FLEW
Put in a stroker kit & turn your 383 into a 480-500 cubic inch motor (or whatever 383's stroke to) and you can get 400-450 horsepower in a very streetable combination. A 440 is another good way to get there, but you already have the 383 motor & it "looks stock"I dont get---- getting 400-450 hp out of a 383?
