383 Engine Build

I currently have a 355 block with a 350 auto trans. and am stroking it out to 383. Here are my parts:

For internals, I am going with an Eagle Street and Strip rotating assembly which includes the following:
-Cast steel crank-3.75 in. stroke
-Forged dish-top pistons
-Forged connecting rods-6.00 in. length
-Plasma moly rings
-Bearings etc.

For the rest of the main components I am going with a top-end kit from Trick Flow, the Trick Flow 490 hp 23 degree engine kit. Here's the link to that:

I will also be putting in a 3000-3200 stall converter and topping it off with a Mighty Demon 750 carb. I do not know what my rearend gearing is.

My first question is if I can get a CR of 10.5:1 or under in the interest of keeping this as streetable as possible. I also live at about 7000 ft ASL, are there any considerations that I should make because of this?
Lay it on me guys, let me know what you think.
Thanks a lot! :thumbsup:

I say sounds good, Im by no means fit to answer any of your questions, but i think that with dish tops, and a 72cc comb. chamber you should be able to get 10.5 or lower, thats just my thought. Sounds exactly like the 383 build im doing, except i went with scat, and a head similar to Brodix. You mentioned you dont know what your rear end gearing is; id say its probably ~3.08, thats what my diff is w/ an auto. if a machine shop is doing your machining keep on top of them, dont let them slack, my engine has been at the shop SINCE MARCH :bang well, good luck to you!

kxplot34, I just got done reading your thread, sounds like youre having fun. It looks like you plan on replacing nearly everything with your build correct? I'm going to try and re-use as much as I can, although i'll probably need a new oil and fuel pump at the very least. The motor I have now was rebuilt about 3k miles ago before I purchased the car and it just doesnt do it for me. This will be my first build and I hope to learn a lot. The only problem is i'm shipping out for basic training at the Air Force Academy in a month and theres no way Ill be done by then. Hopefully in the few weekends i'll get off in the coming months I can come home and tool around on the motor. Thankfully I will only be a few miles from my house. 67vette77, thanks for the advice, but since it is already a freshly rebuilt motor that has already been bored .030 over I dont think ill need to go to the machine shop, well see though. So are there any more answers to any of my questions?
