So I want to know:
If you are typically running on the street a small- small block, say 273 or 318LA and conventional thinking says they do not play well with single plane intakes ( I know people have done it... but without a good breathing heads, a higher lift cam, lower gears and headers and dual exhaust- I've yet to had this work successfully on the street. Single panes just need to much RPM to REALY do their job with a stock 318la motor)
BUT all factory fuel injections use a single plane intake no mater what the size engine or if Throttle body injection or multiport fuel injection.
So if you convert a 273 or 318LA to aftermarket fuel injection say Holley sniper or FI tech is a single plane intake better? O2 sensor constantly is changing A/F ratio?
I know on my 318LA, automatic with a LD340 dual plane intake and minor head work and a decent street cam, dual 2.5" exhaust and the FI TECH throttle body set up... it works "o-k" but not mind blowing. I want to try a single plane to see difference - like "seat of the pants difference". I only have 3.23sg in rear but I have 24" tall rear tires ( kind takes off like a set of 3:55 would with taller tires IMHO)
And what does the 66' Barracuda weight? 3,000lbs max.
Any one have any data they want to share?
