Insane SBF Cylinder Head? Race Flow Development SC2

[@every-istand-ophobe6320]

"looks like an LS head on steroids" yeah it's called a FORD CLEVELAND head and the correct statement is "Wow Chevy made an LS head like Ford did back in the 60's"

[@phillipcaulder8322]

You forgot gm and Mopar stole design for intake and cylinder head from Ford.

[@michaelreilly7977]

Looks nothing like an inline ls head

[@acostaxbmc9580]

Canted Valves Way back in the 1960s when GM engineers began designing the “Mystery” big-block 427 that would eventually evolve into the Mark IV 396/427/454, cylinder head port designers realized that if they tipped or canted the valves at an angle from off-center, the intake flow improved. This created the canted valve head design that made the big-block Chevy famous. This is also the concept that Ford engineers integrated into the Cleveland head design that became famous (or infamous) with the Boss 302 head. The Cleveland and Boss 302 engines may be considered infamous because of their huge port cross-sectional areas. But the concept of the canted valve has not been lost on cylinder head designers. The idea is to cant or tip the valve toward the center of the cylinder bore, which means the valve moves away from the cylinder wall as it opens, unshrouding the air path to move more efficiently around the valve. This not only creates a more efficient air path, but it also allows the engine builder to use a larger intake valve within the same bore size.

[@Stopinvadingmyhardware]

@@acostaxbmc9580 ​ that’s incorrect. The correct reasoning behind the improvement in flow and power is due to the increased surface turbulence due to uneven surface area. This creates a greater amount of laminar volume per surface area than with orthogonal geometry of valve position.

Billy Glidden had a huge hand in the development of those heads for Edelbrock, he learned from his dad Bob who was THE master of the high port Cleveland heads in NHRA pro stock. Clevelands rule and the LS drools. and Randy's car is badass!!! i hope he paints the car to match the rear bumper

So it's a cleveland head? I like when people go "oh LS is so good chevy know what they was doing, big flowing head and mild cam". Ford did that with the 302 Boss in 69. Little late to the game bud. Put a cleveland head on it and send it.

It's a 3.2L 24-valve VR6. The only thing that is stock on the engine is the crank and the pistons. Everything else is aftermarket high performance. I went with 282 race cams Which is going to sound fantastic. I knew a few guys actually running low 900 horses on a stock 2.8 12 valve block. With stock crank pistons and rods. so I should be able to get some good power out of this.

[@ldnwholesale8552]

Aaaarrrrgh. A SBC Chev head is a SBC Chev head. The LS Head is a LS head. Nothing like any Ford head. The canted valve Clevo and BBF is a similar design to BBC head. And the Chev came first!! And nothing else to my knowlege. BBC has the capacity to use the design. Clevos and Boss 302 as a standard engine are probably hurt by the head style. In my applications of road racing and speedway @ 7000 rpm the 4V Fords are simply door stops! No velocity, the 2V is okay but there is a LOT better around in the aftermarket.
