Re: [AMC-List] Heat Crossover

[namdra@xxxxxxxx]

I have to agree with Glenn on using an intake with heat crossover with a
street machine. Not necessary with a strip car but on a street car it
helps with warmup and smooth running. As far as intakes go, I would
choose the R4B if it is strictly a street machine as it gives you more
power from stoplight to stoplight, not that I would ever race on the
street. Yeah, right. I myself really like the Torker for many of the
street/strip AMC's I have owned over the years, it gives you more power
at higher rpm's. Dual quads are nice for looks but not as much power with
them.
