BBC tunnel ram head match
Hi everone, I am new on here, live in UK and need some very quick answers, as im bidding on a 454 on ebay that finishes in 2 hours. The motor is a 454 with peanut port heads, I have a TRx2 Edelbrock Tunnel Ram with rectangle ports and 660 center squirters, will this work on these heads until I can get some decent rectangle ones, quick answers please, will be back to talk when I have more time, thanks

probably too late for an answer, but NO WAY!!! Peanut ports are DONE at 4,500 rpm. Your Tunnel ram won't even come close to matching up with the peanut ports, Its kinda like having a firehose choke down to a garden hose.the reptilian brain is now the one involved

Thanks, I hvae got some Hi Perf rectangle heads for it now!
Welcome to CHR. I think that you need to hook up your vacuum advance. At part throttle when cruising you have less air and fuel in each cylinder, and the air-fuel mixture is not as densely packed...
