370 dyno numbers

Anyone dyno'd before and after 370's? Just kinda wondering what to expect out of mine when i put em in. Im gonna guess im at around 350hp right now as just a rough guess.

IIRC Rick did right around 350 with 370s, 100 plate, 4k, 191s, and a stock clutch that was slipping a lil. But he has a bigger pump (215) I'd guess you'd be close to that.

Thanks guys.

I dyno'd 281/693 with stock injectors, and DV's, and a 3k. I also have a new lift pump now. I am running probably a 1.5 seconds better through the 1/4 mile now, so I dont know how many horsepower that equate to, but ill be finding out at scheid this month. Wont have the injectors in though. Waiting on the tranny

Typically, with enough air, 370's will add about 80-90hp...more with more air!

I picked up about 40hp over marine 300's!

We dynoed a 97 180 this weekend with 3GSK,DDP3's,#10 plate &Hx-35 did about 350hp IIRC

Dynoed a 98 215 with TNT pumpwork, no GSK, custom plate grind, with AFC work and did 313hp, $0 in parts.

A 96 215 with Aurora 2000, 3GSK, No Plate, DV's 370's did, 350hp +/- a few. Dont believe his pump was tuned very well.
