Grumpy -
I have been deployed for nearly 6 months and have been "saving my nickles and dimes." Now, as I near my return, I have time (and cash) to place an order or two and get back to my project. I am at a point where I need some major help in picking a CARB/INTAKE set upfor my SBC 383 Stroker.
OBJECTIVES:
1. TORQUE - and lots of it (or as much as makes sense)
2. Incremental improvements when necessary
3. Frequent - not Daily Driver
4. Try Bracket Racing
5. Return to Autocrossing - been away 20 years!
6. Show-Looks
CONSTRAINTS:
1. "Shop Engine" -- desktop dyno sheet attached (2 bolt mains)
2. 200-4R transmission
3. 4.11 Rear End - newly built VP&B
4. Have just purchased a Distributorless Ignition system - must factor that into the mix
5. NO CARB - INTAKE MANIFOLD DECISIONS -- YET
6. Purchase price for Carb/intake set u $2000.
As an added consideration: NO EXHAUST HEADERS SELECTED --- YET
I've reviewed a lot of the references cited here on your forum and there is a HEAP of information out there. So,here's what I've learned, and correct if I am way off - or on a wrong path.
Intake manifolds -
Dual Plane Lots of Torque -- Loss of high end RPM
Single Plane More on the High RPM - loss of low end Torque
Independent/Isolated Runners Best response all around, improved torque/lowend
AND A LOT MORE NO DOUBT
Tri-power looks "Show Sharp" - but not as much value added (percentage wise) to justify the increase cost over Dual Quads. I was looking at the Barry Grant BADMAN - inline 4 barrel, but recent market forces amy have removed that as an option. But, it does represent a dollar value - about 2K as an upper limit.
I'm am not adverse to Tunnel Rams, Stealth, Air Gaps, etc. I have spent a lot (too much?) time researching old favorites - Webers. So a crossram with side drafts DCOE are a consideration - or downdrafts IDF/IDA on an appropriate manifold. I really like the thought of webers--even though they come with a tuning liability. The big question that has held me up on making this leap is what size for my SBC? And I find little info to sizing except 40 is most likely too small (without a mixing plenum of sorts) and 50s too expensive!
So on to the question - Would you help guide me towards the best $2000 combination (for the CARB INTAKE Choice)to meet the OBJECTIVES, while working within the CONSTRAINTS?
Looking forward to an interesting project!
Thanks Jim
