Glide...also keep in mind it takes less HP to turn a glide internals then a 350 or 400 turbo...my last figure was approx 35hp to turn a Turbo and 6 HP to turn a glide..
so you will pick up RWHP as well with a glide...
the man is right about planateries...over 750 hp..the 1.76 gear set becomes risky....you need to consider some 1.80 straight cut gears...
even if you go with the 1.76 gear set...do yourself a favor and put in a good input shaft...this will go before anything ( normally)..i went with the VASCO HI-FLOW shaft from TRAN SPEACIALTIES and cost me like $280.00...i also went with the 1.80 gear set for $850.00 no problems yet...
good luck my man ..and have fun !
