why cant i make up my mind??

i did all the research to put a 383 stroker in my car, about 500fwhp with afrs 195s yadda yadda. I had it all down and i even narrowed it down to the last bolt but now i just started thinking afr heads are about 1500bux, i think i might be able to piece a turbo kit for that amount and just put it on my healthy 350, why take appart something that is running great?

I am going with a single turbo, this is the one i am interested in its a t76, i am planning on starting with around 7-8psi to get the feeling of a turbo v8, which i heard is nothing like a turbo L4 or V6 (what ive had, hence my user name)

Intake :3.95 inch
Outlet: 2.5 inch
Compressor trim: .80 ar
Compressor Wheel diameter 76.80mm / 102.35mm

Turbine Wheel diameter 72.78mm /64.20mm
Exhaust trim: .81ar
Turbine flange type: t4 flange
Downpipe flange type : 3 inch v band flange
Cooling type: oil cooled only

and the carb i will be going with a mighty demon what size would be sufficient, i was thinking somewhere around th 800cfm area?

so will the turbo be ok? and what size carb?

engine is a 350 with flat tops, 64cc comp around 9.2:1

thanks

Re: why cant i make up my mind??

yes a T76 would be perfect! everyone told me go with a T6 on a 383, if u street drive alot I would say a T4 flage is fine. If I did it again id prob go T4 bc of clearence!

Mine is a 74MM with a T6 flange, see boost around 3800rpm
