I posted a thread below about a twin turbo 383. Well, a slight change in plans. The 383 that I was trying to obtain fell through. A kind member on moparts placed an ad "383 FREE" so I contacted him and got it!
WOW, what a deal. It was removed from a 66 C body that was rotted severely. When I arrived the car was on the lift and was in very bad condition. Well, I got the 383 home and completely disassembled it and Whoa!!!! This thing is emaculate. NOT one trace of sludge anywhere. Valley was super clean, no ridge whatsoever in any of the cylinders. Pulled the pistons and removed the inserts. Hardly NO wear and they are stamped 6-65 on the backside. Same one the main inserts as well. The Forged steel crank still looks polished even. Its ready to head to G&G Machine in Tomball Tx.
So,
Now the dilema! Not gonna go back stock. I have decided to stroke it and add a Single GT45 Turbo. I have been researching the top 3 companies for the 496"/383 Kit for around $2000.00. The "H" company, The MM company and the 440 company. My brother=inlaw is a Heat treater so I had his expertise beside me.
This is the kit,
383 >> 496. (4.250" stroke/6.535" rod) Approximate Bobweight: 2150
Turn that docile factory 383 block into a fire breathing, pavement twisting engine of almost 500 cubic inches, and no one (even the car show judges) will ever be able to tell it's not a 383... until they go for a ride! The time has arrived to dust off those 383 blocks we've been leaving in the back of the garage all those years. Chrysler made 4 times as many 383's as they did 440's, and it's no longer necessary to dig up a 440 block to get almost 500 cubes! The low deck, 4.250" stroke version of our Platinum Series crank used in this kit has the smaller 2.200" (big block Chevy sized) journals, and the counterweights are finished at the smaller "B" engine size, to ensure they will drop right into the block with no counterweight clearancing issues. Depending on the block used, many of customers find this kit drops right in with no modifications whatsoever! We now offer fully chamfered "B" engine main bearings as an available upgrade! We keep all the kits listed below normally on our our shelf and ready to ship, usually within 24 hours!

I have concluded that I will be purchasing the 440 company's stroker kit for the 383. Now I have concerns about the A.R. for the single turbo for this setup. There are several A.R's available on this ebay turbo.
I guess this is directed to "Turbodart" since he advised on the other twin setup but anyone's advise will be appreciated!
Will I need to up the A.R for the single setup since the cubes are quite a bit higher now??? Looks like I can get .96, 1.05, 1.15, 1.32.. Will this engine be able to produce the 800+ HP I am aiming for with the single, if not more?? The engine alone should make 500HP easy. The kit looks to have 9.51 compression as the lowest depending on the heads. I am using the 906 mildly ported heads for now. This is also a blow-thru with a 850 Holley DP.
Post on please!!
