Highest flowing sbm heads?

With all the knowledge and no-how you constantly spew, why don't you build an engine and let us know how it does?
You are like the guy at the car show who spends mega bucks to have a car built than trailers it in and talks to folks like he built it himself in his garden shed.
I should have known my jealous trolls would be showing up, lol.......Ummmm excuse me can you find 1 posting or reply that I ever stated I build my own engines??? Yeah you wont because number 1 I am busy with other things and number 2 there is a HUGE DIFFERENCE in building a 375 hp engine and it lives at max 5800 rpm and a 950 plus hp engine that sees mid 8k on the regular....if you don't understand that then that is on you. I am in process of building the new Demon engine from the short block up as the short block has been done now for a while and then redone again because of incompetent Chevy machine shop. I do my own rear gear changes in my S60, just replace the front band in my 904 when it broke...not a huge deal granted, I do all the wiring and assembly on my cars and fix/maintain them plus tune them engine wise and chassis wise so your comments are incredibly out of line but as expected from you. I also have 9 cars I am actively buying parts for and working on so at times due to that progress from someone looking in from the outside can seem slow and I DO NOT BUY CHEAP **** PARTS....EVER......so that can slow things down some too not only from a financial standpoint but also parts availability deal. Thank you for caring so much....have a great day
