basically im looking at buying :

Hyper Coated FT Pistons 11.1/64 9.8/76 9906HC (i think i need the .030 am i right?) that depends if your starting with a bare untouched block that hasnt been bored already. your machine shop needs to match the pistons you choose.
5.7" GM Resized Connecting Rods (Press Pin Only)
CR3 Rods w/ARP Bolts (i think this is an upgrade for the above)
Street/Strip Cast Piston Rings
King Rod Bearings
King Main Bearings
NEW Cast Stroker Crank what brand is this that engine kits.com sell?
Full Gasket Set (2-Pc. Seal/Carb. Only)
Moly Rings
Balance (Inc. Flexplate, Balancer, 2-Pc.)
Fel Pro Gaskets Upgrade to 84' 2pc Seal

thats the kit.

fairly small cam choice for a 383. what is your goal for this motor?
Product Description

• 290°/300° Adv. Dur.
• 112° Lobe Center
• 71° Overlap

• Idle Quality: Fair with lope
• Power Range: 2000 - 4800 RPM
• Good choice for light towing
• Recommended spring pressure 110lbs. for valve on seat; 280lbs. for valve open
• Compression: 10.3:1 or less
• Transmission: Stock auto or Manual
• Recommended for mild bracket racing

Heads:

60739
Edelbrock
Chevy 302, 327, 350, 400 Cylinder Head, Performer RPM, Aluminum, Assembled, 70cc Chamber, 185cc Intake Runner , Straight Plug
35 LB

and a edelbrock performer air gap intake manifold.

im assuming if its an 81 your also saying goodbye to the computer,carb,dizz and loc up converter?


please help cheers

Looks like a nice 380-400hp combo. You will get a lot of opinions on your cam choice and the decision is up to you, but know that bigger is not always better.

here is what i think...

thats quite a good run from an 81 motor to still be untouched. not even 30 over? it will be a 2 bolt motor .what cam would you recommend for it?most on here will demand you go to a roller cam. if you do go roller i would recommend crane cam 119661 . its a small base circle cam that suits a 383 with no clearance issues. its from the powermax series and with your combo will be making no less than 450 hp with 450+torque. you will need 10-1 compression and prob a 3000 stall but will get away with a 2500. if you go in the direction of a standard hydraulic 490/490 is about all you can go before you need to clearance the block.
computers going carbs going dizz and putting an older th350 trans in. or would u go to the 400?? there is nothing wrong with a well built TH350 - heavy duty sprag is a must . at least it just slips straight in where your old Th350c was without any mods. sure you could go to a 400 but thats another cross member and shorter driveshaft etc etc.
i believe the makes powerhouse. it ses its a powerhouse stroke kit ok i cant comment on powerhouse, dont know much about them. im sure someone on here will chime in with experience

with your engine i would not take anyones word on anything until you have seen it with your own 2 eyes. i would strip it down to a bear short motor. check it over for sleeves or any damage to the cylinders where it may have thrown a leg out of bed once. have a machine shop go over it completely and measure it up to see what you working with... then you can be assured that this will make a nice,safe 383 block.

skat or eagle rotating assemblies are very popular and well priced. since you starting from a bare block i think 5.7 rods are the way to go.around here i know ehere i would shop for my next 383 kit but im not really in a location to recommend one for you. i do know that cnc motorsports has a good reputation and alot of choices in 383 kits.

-the cam is definatly a sweet piece for good power and nice driveability and with a 383 its going to be all smiles. it requires a cam button yada yada but roller is the way to go. no headaches of cam run in,special oils,wiped lobes but also this is just my choice on cam for a 383. there are thousands of choices out there and everyone has different tastes.

- the transmission is an easy swap and should have a warranty. that all depends on your budget and time as there are many more options out there with overdrives transmissions etc but with that comes modifications and $$$... this just depends how far you want to go.

-powerhouse 383 kits i cant comment. i dont know of them . someone else will have to chime in on ft pistons etc.

i am at 436tq at the rear wheels and my build is way more...it is not that easy, .... cam... .500+ duration on exhaust/intake should be greater that 235 @50* got to go aftermarket heads or very good porting and polishing and port-matching... good long tube headers and good exhaust... big carb....

but you dont get 450 hp with just a mild cam change and a basic engine rebuild which this is.

and if you go flat tappet, you are asking for problems.... and less hp

Hi Scott-
I ordered and installed the Powerhouse kit almost identical to what you describe. I, however, retained the original 76cc heads which I had reconditioned and used the flat tappet cam supplied by them. I only have 205 miles on it so far but am all smiles. In city traffic I drive it like a powerglide, 4 speed using first and fourth only. Plenty of low end torque so not a lot of shifting required. Light to light using all four gears is one helluva lotta fun. Make sure they balance the rotating assy, they balanced mine and so far it's the best running motor I ever built. Good luck

There is no way you will get 450hp out of those heads, even with the 119661 cam. You want 450hp, pony up for some AFRs.

what i think again.
Originally Posted by pauldana

Duration @ .050'' Lift: 230° Intake / 238° Exhaust
Valve Lift w/1.5 Rockers: .539'' Intake / .558'' Exhaust
Lobe Separation Angle: 112°
i dont think i would call it small and i think its a good match for a 383 . if it had some fastburns or afr it would make 450 hp in a 383.

and what kind of intake? he said rpm airgap above in his original post .carb? exhaust?

for what is there so far, i would put him at around 375hp max... unless head work, and bigger cam....

None of this stuff is purchased. I'm looking for suggestions before I buy. Cam has been
changed for the crane cam suggested. Also think I'm gunna go for the stroker kit suggested. As for heads if u cud say which model I'll look into cost. I have an edelbrock
1406 carb which I don't think I'll b using as I believe it's to small. Exhaust will be changed
aswell so no exhaust either.
