Say I get a tr220 .551 112lsa with 28000 stall... What E/t should I expect to hit? What about if I were to get 1.8 rockers as well?

 

if u get the tr220 then what r u going to shift @ it better be high like 6800 to 7000 a friend just put a cam in a 4.8 and ran 13.51 with 3.37,a good tune and shifting @ 7k and high rev @ 7500.with 3.37 u will stay in 2nd gear shifting @ 7k and will be faster than 4.10 shifting @ 6000.i would put rod bolts and @ least shift it @ 6800.

 

Nice!!! Well Ill have see what I can get with my 4:10's.. I may take it to about 7200.. If it can handle it..

 

that stall sounds kind of big. sorry I couldn't resist.

 

Do you guys normally rev those engines that high??? I presume that is with the stock Hyperutectic pistons... which I would think ought to be limited to around 6300 or so.... I have yet to calculate piston speed for these engines but Hypers are only good for so many RPM.. I see cracked piston skirts all of the time on overreved engines..... just curious
