383 advice
I decided to build up my L98 to a 383 stroker. Just wonder what direction you guys went with on you 383 strokers? What is a good set up? So far I'm deciding on a Eagle or Scats rotating assembly. Not sure which way on the heads, have mine done or AFR heads. Cam is in the air due to emission laws so not sure which one yet. I'm going with the Super Ram intake and manifold but not sure what size injectors yet. As far as clutch I'm probaly do the center force (have had good luck in the pass). I'm throwing things out there so you kinda know the direction I'm going. But any other opinions, advice, other brands you like to throw at me, great. Right now I'm doing the research before I start buying the parts. I been hanging around a bit and know when it comes to corvettes this is the best place to be and there are many knowledgeable owners here. Nothing like that corvette passion. So what do you think am I heading in the right direction so far? Thanks for your help in advance guys.

I still say if your bottom is good leave it alone and concentrate on the heads and valve train. With the money you'd save not doing the bottom end could build a wicked top end that would get you there.
Then if the bottom breaks hopefully it's after you've regrouped you could do the 383.
You could always just "freshen up" the bottom end with some new bearings, ARP fasteners, oil pump etc.. and still be way ahead of the game. Then spend the extra saved cash on headers and full free flowing exhaust. You have thought about exhaust right?
No way I'm breaking into my bottom until I know I've gone as far as I can up top.
It's still just my opinion, if you have the money to spend do it, I'd just take a different road.

For you in Cali, SR-219 cam-AFR 195 heads-24 or 30lb injectors depending on what your chip tuner says and what bottom end you end up with.
SR has CARB, 219 can be made to pass the sniffer.
Only problem you have is exhaust. California leaves your options limited.

If you know a inspection station that you can "pay off" then long tube headers are the way to go. I know its done on a regular basis there so find yourself a unscrupulous inspection station operator that will sign off on headers.
With saying that, the AFR 195 CNC ported heads, SR, LPE 219 cam in a 383 is a proven combo that will easily get you into the 11's. Make sure that your static compression is no more than 10.5:1 max.

If you plan to pass emissions, you won't pass the visual test without the stock front Y-pipe, you might make it by with some shortys but longtube headers will not pass the california visual. I guess it depends on who you know and what county you reside in though.
the combination i listed above can get you the power you want and alot more, well over 400......you could go with slightly smaller (or cheaper) heads and not lose much with the 383 underneath

I'm in the process of building a budget 383 right now, but I don't think I have the same goals as you. I wanted a very torque-oriented motor since I have an automatic and my Vette will be more of a cruiser than a strip-terror. Figure out exactly what your goals will be before you start to build, or you will have to do re-work later...

Torque is the king my friend. If goal for torque: than u would just love strokers, install small duration cam 215-220 and prefer more lift, dont go for big AL heads not more than 195 CC on a 383, shoot for high compression between 10.5- 10.9:1.
Mine is a 383/219 cam/200cc dart pro heads/ SR intake. I just love it. Wish i had go with more smaller Heads like 185cc than i would call a tor monster.

I've got plenty of torque with 210cc heads and then some. I have not tested this combo yet on a dyno but I know my aZZ knows its there. Great torque, long winded, and pulls strong all the way to 6000rpm and beyond. This coming weekend in Sturgis, SD I'll be there for the Black Hills Corvette Classic to do a little drag racing. I can't wait!!!!!!
