Default Which Huron Speed Turbo?
It's decision time for my build and I'm hoping the gurus can help.

Goals are twofold and in this order:

1. Streetability/spool
2. 1000hp at the crank on E85

5.3 stock block
PRC Stage 2.5 706 heads
TSP 224/228R6 114 cam
Fast 102 intake/tb
4l80E with Circle D Multi Disk Billet 3200 stall

All going in a 1966 F100 which has a curb weight of about 3400 lbs.

I'm thinking it's between the Turbonetics 7575 Billet BB or the Precision Billet 7675 journal bearing. What do you guys think?

ive heard great things about the Precision 7675. i was going to run the non billet one at one point on a 346 and was told they spool up FAST! since then i went bigger motor, bigger turbo, but id imagine the billet would spool even better.

I had a Precision billet 7675 and it did spool pretty quick. Made 705 rwhp until I started running into issues with it being to small for my motor, 383.

7675 is small for a 383 but a pretty good size for a 5.3.
