We are still in the middle of our 400 rebuild and are considering buying the 80pis pump from butler vs the 60psi one. any thoughts on this? Also we have gotten a different set of heads through the grape vine. They are 46 heads off of a 428. they have the small valves and i believe they have 72cc chambers. Would these work better than the 7J2 heads that are on our engine? The 46's have the area to drill and tap end holes for the hooker headers that we bought so if we can use them that would be great as we got the heads for 12 bucks more than the L brackets that people use to provide end studs for the headers, honestly I would like to drill and tap the 46s. Willl the 72cc chambers kick our ratio up to far for pump gas? I think the 7J2 heads have an 96cc chambers not sure if they will work for us. Hope you are having a great day and thank you for making all these videos.
I lost my 421 ho due to a failure of the oil pump gasket
