New Small Block Headers

Scavenging was only mentioned on engines at 350 cubic inch or less and at a maximum power of 400 horsepower. I don't want to name the header manufacturer but they showed were the smaller tube scavenge the cylinders better than the 1 5/8", although the 1 5/8" is still a good size. You simply can't compare a top fuel engine to a daily driver as you have as they are as different as night and day. I think that you guys on here are so much into high rpm high powered engines
Power depends on the build and intended use of the car. Along with selecting the correct cam for use. I’m about lower rpm, so I can pull hard out of the turns with a 4 speed. I’m going to be at Laguna in a few weeks and am going to talk to and talk more photos of the transam cars. My brother knows a few of the guys the build and prep them for the vintage races… I’ll take photos of the headers also….
