But those heads willВ actually lower compression compared to using heads withВ smaller 60cc or 58ccВ chambers. The 461 or 462 'fuelie' heads have a larger 64cc combustion chamber and do flow more air.

This is going to be a very mild 292 in my street rod and I might even add a Rochester tri-power setup on it to give it an old time hot rod look.

The best part about the 4L60E is that it's electronically controlled, eliminating the need for the finicky TV cable the 700-R4 uses. Jeff says it has similar gear ratios to the 700-R4 and it will bolt right in place without sheetmetal modifications. What would you recommend as a good replacementвЂ”a TH400 /TH350, GM 4L80E, or what?'The recommendation is.a 4L60E.

Will need for the conversion as well as the pros and cons of the Turbo 350/400 and the 4L80E.
