Mild Thunder your engine build would be great in front of some 20 hour Johnnyboatman drives! You should think about it.

Good Idea, but may I suggest timing your engine off of cyl #2, you will accomplish two things first your timing will be backed off, and your engine will run warmer to compensate for the cooler lake temps this season! Just sayin also as an added benefit you may be able to see your exhaust valves glow right through your heads.

I want a tall deck 396 with a 3.76 stroke and some peanut port heads. My max RPM I would like to spin is 4000. I have a 2 barrel rochester carb for it. Its gonna be 11.5:1 compression with an RV cam. I plan to run it on 87 octane with projected tip plugs, cast pistons, 210* water stat, and 39* of locked timing. Shooting for an air fuel ratio around 15:1, for good MPG. I am hoping for 650hp at 4000rpm. I really need the midrange cruise
Ya could sleev'er run some off da shelf close chamber 396 pistons on a .400 longer rods to help out with your longevity issues, but at dat point' ya'd prolly be better starting wit a 427 tall deck, dey got ticker walls in'em. Ya know on the subjecta termostats using da stock truck intake you gets two thermostats! Ya can putta 160 in one side of da housing anda 210 in da udder. Den yer covered fer both seasons, post fire wood cuttin, and pre fire wood cuttin.
On da subject of carburation, I tink a center carb off a mopar 440 sick pack is sumtin like 7 hunderd cfms, dat wurk perty good too! My cousin squirrley eddie had one of dem carbs on jeep commando and lemme tell ya he could smoke all 4 tars on da pavement, it'd really trow back in the seat when he'd hitt're even with da plow on it!

For the price a 671 IMO would be a better value and an intercooler wouldn't even be needed. Not sure if 250s would bolt to his intakes but that could save some cost if they did. You could really be cool and run higher compression with plenty of boost and E85

If you window the block and dry sump it it reduces windage. Helium filled rods are a good addition too...well worth the money.

I'm gonna be installing dual 4" electric superchargers I bought on Ebay for less than half the price of one of those ol-fashioned belt drive models.. Where can I get some matching electric blow-thru carbs? I really wanna do it right..

What are you guys thinking. Every single one of you forgot to suggest a couple of bottles of 104+ Octane boost. I gained 4 mph when I put that in my gas. Not to mention it turns my 87 octane into 104 race fuel, My engine also has the special 13:1 deep dish blower pistons as mentioned in an earlier post, nothing can touch my boat on my lake, it runs like a raped ape! Walmart has 104 on sale form time to time, best performance enhancer I ever did!
