Sonny builds some great stuff and is a super nice guy!
Way back in 1998 he built a n/a 437 c.i. fuel injected (Motec unit) motor for my B/A NHRA car. It made just over 1100 horsepower with a great torque curve. We went a full tenth of a second faster than the national record with it the first time out testing.
Only two problems with putting that motor in a boat:
1. We shifted at 9700 RPM
2. we rebuilt the motor every 10 miles.:eek:

Love to see some of the big power turbo guys get into boat motors, but it is a whole different game for sure.

With the increased bore spacing you can make huge power with no wild angles. These new blocks are going to change allot...

Sonny's Engine .......Larger crank journals.....bigger bearings to handle the increased displacement?

SummerObsession....Your Skater is over the top!

I help out on a car that has a 865. Carl Foltz wedge head. 11.7:1 compression motor makes 1850hp before we start spraying. Sonny builds a good head and it would have been about 10g's cheaper to run his stuff but the car wouldn't be competitive. We spin the 865 9500rpm. Motor has been together for 3 years with same pistons and crank. Ran a best of 5.96 in 1/4 on 3 kits of nitrous. One more kit to go but car isn't ready for it. I think that says alot about today's part and technology.

The 865 has standard Chevy journals and bearings. Callie's forged crank...

Thank You
