Looking good, I would have never doubted that. If you keep it from detonating you will find the limit of the rods soon enough, with that kind of rpm. Get any closer to 825 and we will have to take the little 74 off the GTO lol.

viper spec'd T56 with ram VDS clutch and a 9.5" 14 bolt rear with 488s
im thinking of rebuilding a 4.8 with 5.3 dished pistons and using some 241 or 243 heads. also for a budget turbo build. did u know, speed pro has replacement pistons for around 400$ with rings. they come with grafal coated skirts. i have used these 6.0 pistons in a 6.0 rebuilds with my own dd and puttin down just under 500rwhp, with some 5.3 stg 2 heads they go up to .060 over and are available in 4.8 with flat tops and the 5.3 with dish. 6.0 are also 8cc dish |

from the graph, it doesnt look as laggy as I would expect.
this makes me rethink the 76mm for my 283.

If you get a TC76 I don't think it would be a problem....esp since 283s like RPMs  |
