Baddest pump gas NA small block?

[Uncle Dave]

Thanks I went through a bunch of combos before settling on this.

Yes I have a video of it on the hose at boostpower somewhere Ill dig up.

Pretty docile, but lumpy enough idles at 850 out of gear and about 600 in gear so not to much bravo "crunch"

Its also pretty quiet with the exhaust underwater at idle.
You can hear us bit-chin about a used part we drove across town to buy that was a basket case while we idle out.

3 dudes 2 chicks- bad ratio - lot of beef on board.



Heres a clip from the back with a water proof go pro while we were picking props and tweaking the setup.



Your avatar is a jet ski but dont you have a completely wicked blown alcohol flatty or something like that?

I like it Dave! The boat's not so big that you loose the excitement and yet it will handles fairly rough water and can likely pull your head off in a turn.

A really nice overall package.

Yeah, I've got a nearly useless, impractical trailer queen that cost as much as a middle of the road DCB or newer wake boat.

Thanks!

I spent 20 years tweaking it with liberal infusions of cash. It works really well in a suitable environment.
The rigs turning is like a slot car, and with well over ten g's into the ITS and juice helm it should.
That same system easily turns my 28ft V.

At the right place and time there is nothing like a wicked big block in an itty bitty boat.

Next time Im at the river you can take it for a spin.

Cam is Engel GHR-236/242 on 110 lobe centers (vs standard 114)

Its advanced a bit - I think 4 degrees.

Some of the younger builders like Bob Madera and Alexi seem to have even sweeter combos that make even more HP, but I don't know if id get 10 years out of them or what more I would have paid upfront.

Dick was a treasure trove of info but was as hard headed as a mule and rightfully so.

I have a pretty decent piece in my chevelle, car not boat so its a totally different world. True street car though, easy to drive and no need to pull timing or any tricks to get it to go around town. Drive over 50 miles each way to the track at 4k with the gears and am good to go.

splayed (sp) mains and girdle
421 CID
6.2" rods
JE pistons @ 10:1

Heads: World Products sportsman II's 200cc runner, 72cc chamber (all when stock)
now has 2.05" intake and 1.64" exhaust
Bowl work and some other "stuff"

cam: solid roller
lift: 601/625 and then a 1.6 rocker on that

Hoping to have some dyno numbers in the winter for it finally, getting ready to run True Street in the NMCA for the experience.
