This guy knows his shit! Holley Carb Secrets. Yet I made more power where needed and had the faster car.īobIn these times the info is out there. I ran oval port BBC heads and made money off others running rectangular. Those who do flow rates do not understand. squirters, front and back jets, power valves, linkage, plate edges, rod thinning. jets, slide cuts, needle tapers and more. Tuning a carb is also an art that few have enough time into to do.īikes. Sitting where the carb was is just a fancy carb.Īlso here with the inflow wet a mirror polish maybe not so good as one needs to keep the gasoline in suspension. May depend on where in the stream you inject the fuel. Many benefits to running ally heads.īut, some of us still like to play with old-school iron. With Trick-Flow's probably being king of the hill. I play with the 516's for the closed chamber, and squish properties.īetter have your tune on point though or you will rattle the pistons right to death, LOL.Īnymore most everybody runs to one of the excellent aluminum offerings. But the 915's and 906's are still very relevant. 452 castings are probably most desirable these days for the induction hardened exhaust seats. Max Wedge heads were pretty damn serious power makers. Basically the big-brother version of a SBC head. Stan Weiss' - Cylinder Head Flow Data at 28 Inches of Water - DFW / FLW Flow Files for use with Engine Simulation SoftwareDamn straight B/RB motors are still a thing! Some of the best muscle-car era heads ever. Anyone ever do Max wedge head castings?ĮDIT-"snowshooze".Went down the "B" motor rabbithole.gonna have to broaden my horizons beyond SB Chev.The "B" motors are still a "thang". Am surprised that there would be enough demand for CNC ported "B/RB" motor heads. Hemi 8 bolt flange crank, lots 'o compression, Milodon swing pickup-4 speed car Crossram and Max Wedge heads, and not that they needed help, they were ported.

I don't understand what you are trying to say? But it is making zero sense in the context of this thread.Īnd it is painfully obvious you do not know how to tune a carburetor.Īh, the 426 wedge. You will never increase the air-flow potential with the fuel delivery system.Īnd you will never increase max potential power choosing FI over a properly tuned carb/s. You slap the newest whizz-bang FI system on a ZZ302 chebby, and guess what? It ain't gonna make any more power to speak of. It is 100% because of engine architecture, including ports!

Yes newer engines make gobs of power in comparison to yesteryear.īut, it is NOT because of the fuel injection. Not saying porting is 'bad'įull emission cars are running much higher horsepower per cubic inch than the fanciest ported an polished carbureted cars ever did, and they idle, start from cold and don't stink.Īnd they aint polished.In red ^^^^^ Bullshit! WRONG WRONG WRONG You can add more horsepower with a good fuel injection tune than all the porting you want. Fuel injection and be programmed to eliminate that.

On a carbureted car large ports cause low velocity and poor fuel distribution at idle. Computerized fuel injection is more cost effective than playing with porting
