Before BBlades cleaned up the prop, she was turning ~5300 RPM in the low 60's but I assume once the dyno is done and some sea trials, I can dial in the prop more appropriately. I will be using the timing set that is included with the Cam kit. It looks like the CR will be around 9-9.25 when all said and done. The ilde was pretty high before ~800 RPM and I usually have it around 1100 when moving around the docks.The SM manifolds have tails that almost touch the tips on the thru hull (~2.5 Inches), I was thinking of setting the initial ignition timing at 10* but since I will be using the dyno, I will get to play with it a bit.

The rpm ranges advertised aren't that useful. I would think you would make max horsepower at 54-5500, but the dyno will tell for sure. Careful on your max advance and run good fuel.

Sorry to go off topic, but I like your fauxtina C-10.

I own a couple 67-72 myself :)

here is a used one at the fraction of the cost.(i got mine on ebay for $100)

Going to be starting a similar project with my S10.... race weight of 2800 pounds and is high-10s capable as she sits. Really loving the idea of a cheap 5.3L turbo set-up to go 9's. My understanding is the 5.3L short block is 1200 HP capable.

Back to the thread...

Josh,

Comp is rather weak in the lift department, and I'm not a fan of their cores. A big block Chevy with decent heads needs lift. I would look at some
crane offerings. The 731 (or equivalent) is a good choice, but requires you to spin it a little faster (5600). Just my thoughts.

I just put a 168761 in my 454 mag. Hoping to dyno soon. I had a comp cam similar to the 168731 that peaked out at 5200 previously.

LOL. No. I don't care what Hot Rod magazine says. ;)
