Thread: Tunnel Ram pointers

Tweet

I'm tryin to put together a SBC T- Ram motor together. Thinkin about 2 390's and low compression for pump gas. Any comments about cam choice? I am sure this is a combo that some one has experience in. Any input would be appreciated. TKS

I'm running a SBF with sync'd Holley 390's (4160 series) on a Weiand #1988 Street T/R intake, with hi-po '66 289 heads at 10.5:1. My cam is fairly mild. I'll be building out to 331 soon (yay, eBay!) and will upgrade the cam to a Crower Level 3, but intend on keeping the dual quad tunnel ram setup.

The biggest problem was having to rebuild the carbs completely to get them to sync. Now that that's done, it runs killer. Idles sweet, goes fast, sounds great, and all that engine is a real head-turner sticking out of my little car. Runs on cheap pump gas.

Most of the negative things I was told about running a dual-quad tunnel ram seem to only apply to overcarbed engines. If you're running 390's, you should be streetable no problem.

I have built sev tunnle ram engine's what I have found to work is build the engine around the intake and carbs depending on what intake you use get a cam to match the rpm's of the intake and when you say low comp. how low are you wanting to go and also with a tunnle ram get a good ignition but a SBC should handle the 465cfm carbs a buddy of mine has 2 of them on a 400 sbc and it runs real good. good luck
