mid 11 383?

I am currently wanting to do a 383 stroker for my S-10. Its a 2001 xtreme, and ever since I was a little kid I have always wanted a show truck with serious old muscle. well I got my change, I purchased this truck and now im ready to modify. I absolutally love the older style engines and decided to go carburated instead of new age (LS1) based motors. I want to do a supercharged 383, I already know that I have to have a forged bottom end and really beefy at that, already have a cage built, its been tubbed, new tranny, driveshaft ect... ect... anyways, I want to know if its feesable to make a mid 11 second s-10 (3850 with driver) with a blown 383 for a decent budget? I am going to start with a bare 4 bolt main block, forged steel 4340 crank, forged rods, forged pistons wiht a combo of a 72cc 2.02 /1.6 lift head set to end up somewhere roughly around 8:1, I think I want to do a 6 71 blower, not sure if that would be efficiant enough, and a blower cam somewhere in the range of a 5.20 lift, does this sound like a combo that will get me near mid 11's?

What heads?You will need more cam.I would look for a mech.roller cam, a little safer than a hyd. roller at higher r.p.m.'s.

well I believe my budget is somewhere in the range of $3500, and I know I can get an extremely strong bottom end with a 4 bolt block (short block already assembled to 383 all machine work done) for around $2500, without cam, so I would need a cam and heads, leaving me in the $1000, I really would go as far as to spend $1300 for a cam and head set, I would like to go iron, just because of the blower, I guess I didnt mention I am going to run somewhere like 10 lbs out of it too, not sure if that changes anything, I cant find a twin screw for an older style carbed 350, if I could, I would most likely use an intercooled twin screw at 12lbs

you can put a blower with 6lb. of boost on junk and run mid 11's. :eek:

"my budget is somewhere in the range of $3500"

You must be using some new kind of math. If you spend $2,500 for a short block and $1,300 for heads and cam, where is the money gonna come from for manifold, blower drive system, blower, carb, fuel system, cooling system, headers, rear suspension system, slicks, etc., etc., etc.????

thats $3500 for the total assembley of a longblock, im going to put it in just as it is without a blower, and I have someone lined up wanting to pay $3500 for my old motor, herefore giving me money to play around with for the blower, this is just the budget for the engine ONLY, I already have a 4 link susp. done, its been tubbed with big slicks on the back, ford 9" rear end, chrome molly driveshaft, full frame has been boxed in, and the swap parts are parts in a budget of their own as well, as I see it those parts inclue: radiator, fans, headers, mounts, and ect... any other parts needed. understand now? I am spending BIG money on it I know, but it was my dream since the first time I saw a car with a blower, and a 9 second s-10. so do you think I could get mid 11's with a 6 71 blower with a pretty big cam and a good set of iron heads?

Forget the blower. If your goal is to get into the 11's, a 383 with AFR heads, Victor Jr intake, and solid roller cam can easily get you over 500 hp and 500 ft. lbs. of torque. And it will still be very streetable. Spend the rest of the money on the suspension, tranny, and rear end so you can get that power to the pavement. You will be quicker going that route.

^ already have that money invested, read, I have the rear end, full custom 4 link, tires, its been tubbed, already have a cage installed, new driveshaft, new tranny, all that, and I wanna go with a blown motor anyways

Sounds like you are ready for a blower motor. Most blower companies like BDS will assist you in choosing compatible engine parts for one of their blowers. You might check with BDS, Dyers, and others if you have not done so already. Sounds like you are on top of it.

Got Pics.?

rumrumm is correct. Lean on the manufacturers for help. Here's a list of all of them that I could find....

I am pretty sure im gunna go thru BDS, any suggestions on a cam? any incling as to what kind of numbers im looking at running with 10lbs from a 6 71, and that setup? not sure what heads yet, something not like over the top, I wanna keep it still like just streeatble enough for a weekend cruiser, and I dont have to worry about emissions, its going to be listed as a hot rod

Click "tech info" on the BDS site for cam recommendations.

Click "dyno tests" at the top of this page, then click Chevy tests, scroll down to the test on a 383 with a Weiand 6-71, 690 horsepower. If that won't convince you to buy AFR heads, nothing will. Also check out the cam specs they used.

well thats a LOT more than I was expecting, tho I am built for over 1200 horsepower, still, thats a HUGE number
