Oh I didn't say we had the funds...lol. The costs for doing what they are doing seem to be fair....at first I had some sticker shock but once I sat down and went through the estimate...it all seems in line.
VERY cool read!

Things are going well. Reggie PM'd me and said sea strainers are being fab'd and custom water pickups too. Tyler is making full dyno pulls on second motor tomorrow...and we hope to have both engines to RF by end of next week. 7 blade Herrings on on the way.
Gonna have to probably raise drive up on transom...Reggie Jr and Sr say it needs to be higher to go FAST FAST FAST!!! LOL. Spacers for SCX and 1:35 gears are coming from IMCO. Keeping fingers crossed for 120MPH.

Tyler is putting together the second engine now...we kept the stock 525 heads..had them ported and polished..and they flow as much as they can....the increase in cam spec is maxing them out. Next step would be to get a set of Dart Heads to help it breath a lil better. Im not sure of the new cam specs.....Maybe Tyler can chime in on the detials of the new motors.

I just got back last weekend from Tyler's shop. One of your motors was finished up and Dave was building the second one when I was there.
I took a 4.0 whippled 8.2 to 1 540 down for a tune.
Using a little less cam than you ( 268741) but using AFR 357cnc heads, the increase in torque and hp over your current set up made the heads the obvious hold back on your motors.
We compared the dyno sheets side by side and there was a nearly 150hp difference and almost the same diff in TQ numbers.
Discussions led to the call you got from Tyler in regards to heads.
You can go less cam ( easier on the valve train ) and make more power with just an out of the box head swap.
980 is nothing to sneeze at for sure but the power is sitting on the table, you just have to want it
Good luck with the project. I look forward to seeing the numbers when its all done.
