I like to run my boat hard, I have had good success with my BAja engines after learning BBC, may latest engine went boom after being ran hard for 6 miles at 5600, leads me to now....
on my current builds as you know I am going for reliable and good parts, not top of the line but good, guys say I am gonna regret going 650-700 hp because that's going to be unreliable, I disagree, I think I am making good choices to be rock solid reliable engines, I am not chasing every last single hp, and they make whatever they do, but I am trying to maximize what I do have.
guys say blowers are not reliable, not true either, it's all about quality and maintanence
The biggest issue I see is guys trying to save a buck, or meet a timeframe goal, I tried that in the past at both and failed. This time I set in my mind it's done when it's done....

Sometimes, its nice to put the opinions aside for a moment, and hear what is working for others. Keep the stories/setups coming. Even if it was a failure, its worth talking about.
My general setup.
468ci mark iv engines 8.9:1 compression
vintage Dart 308 Race series alum heads, bowls blended and valves unshrouded, 165 seat/450ish over the nose isky springs. MLS head gaskets/arp head studs
crower 236/245 .630 lift 114lsa cams
morel lifters 4603
crane rockers
.135 pushrods
JE pistons, manley rods, chevy steel cranks,
B&M 420 blowers with twin 850's, 6lbs boost holley mechanical fuel pumps
stellings headers with dry tails
dynoed 804HP @ 6200 and 735ftlbs
msd distributors with crane ign boxes
No water stats, oil stats with bellhousing coolers
air fuel ratio low 11's wot, timing locked at 34* (although changing to daytona sensors with custom 3d maps this year)
100 hours on this current setup with lots of wot time in a old 38 non stepped fountain with huber trannys and #4 drives. Prior to rebuild engines had lots of time on them, but with smaller blowers and less power. either way, So far so good on this combo.

No intercoolers. Blower is 7% underdriven. Have considered adding them, but going to check temps in the intake manifold this summer via an IAT gauge. Just some budget motors, nothing fancy. Someday I'd like to build something cool!
Cmon guys, I know there's alot of bad azz setups out there being ran hard......
