Thanks 357, Not yet on the platform...The engines are just broken in and I can only get up to 57 at the moment but that is at 4400 with 4 blade 24 pitch hydros and a fould bottom so I'm sure once I get the blowers on I'll be able to turn them up to the right rpm (looking for 5000). Kind of planned this whole thing this way, via the lower compression, just could not afford the blowers this year. So I'll have to live with the 57 for now. How fast is yours? What is the norm for this hull?

Nice looking ride!! My 86' 357 with spruced 420's & Kamma's so far on flat water have seen 65 on gps. Need some chop under these heavy- weights to see good numbers. I am interested to see how you blowers work out. What compression are you running? What mods gave you 500 hp on those 420's?

Yours looks nice..I almost picked up an 86, I like that paint scheme. The Engine's are as follows, fourty over with speedpro forged .100 domes with Merlin large ovals, I ported and polished them right out of the box and smoothed over the cumustion chambers. The cam is 515/520 lift dont have the duration #'s with me but Dennis Moore set me up with the sheets and he said 490/500 horses. I wont know the true potetial for these engines untill I put the superchargers on them. I am anly at 8.2-1 Comp ratio right now. I plan to run them at 3.5 lbs. of boost to start. I travel alot with this boat so it must be very dependable. You have 420's?

yes 420's. Crower Cams(don't have specs) and performer rpm dual plane intakes. I run them 5200 rpm. Would love to have about 100-150 more hp. This would greatly improve overall satisfaction. I also travel long distances and need dependability. I've heard good things about the 420's built with blowers. Can't wait to hear how yours turns out. Keep us posted.
I'm looking to make a trip to your neck of the woods next summer. Detroit to PI bay. I heard it is a fun trip with lots of surprises and shallow water. Haven't boated in Erie yet but looking forward to new sights.
