So, this year we were asked again if we could help out with another engine, for another boat, to go in this years Semper Fi raffle boat. With the great success and huge donation that was able to be made with last years boat, course we said yes. This year, since I actually have a little time, Im going to do a few progress updates and pics of the engine as we go along. One, so people see what they are getting with this boat with their raffle tickets... and two, to help keep this project for a great cause, on peoples mind so hopefully, yall can make it out to HP Fest in November, and buy a ticket... or ten.

This year were building a nice, solid 408 cubic inch Big Block Chevy... nothing overly exotic... just a solid 420hp single carb, pump gas, reliable runner.

Also... I, personally, would like to thank fellow SCJB member, Ryan Carnahan for the donor short block that was originally in his 19 Charger. With all forged internals, it was a great candidate to build from.

First step... after cleaning, mag checking, and inspecting the block, crank, and rods... the block was put in our Sunnen line hone to have the main bores trued up, not only for size, and roundness, but to ensure that the main centerline was established. This is what pretty much all further machining operations are based off off, index surfacing the decks and boring the cylinders.
Here is the block after line hone, getting the second of many washes in the jet washer...

This is the first of many future updates...

Yes, those dates are still a go, but to clarify those aren't related to Horsepower Fest.

A short update: block now completely machined and washed up. Line hone done, decks indexed and surfaced, and cylinders torque plate honed to final size. Crank checked out good, so well give her a polish after balancing. Probably another week or so well get the rotating assembly balanced (with pics) and start assembling the short block. Also... at some point here, well start some progress on the cylinder heads. Im still a little aways from porting them as I have 3 sets in front of them... but as soon as I start, well get some pics of that up as well.

Been a while... but here are the heads... they got a nice little port job, bronze guide liners, hardened valve seats, 3 angle valve job, and cc & surface. Want to thank Schneider cams for the cam hookup... she out to work good in this little pump gas mini big block.

If I could figure out how to post videos... I would of it running... 🤬

Just like to thank folks who contributed parts and pieces to this build:
Ryan Carnahan for the 414 shortblock
Travis Kennedy for the head cores
Kevin @ Schneider Cams for the cam

Shes a nice little build... should be right in the 410-420hp range. Its a .060 over 402 Chevrolet 2 bolt block with 3/8 Arp bolt rods and TRW pistons cut to 9.5:1 compression, with ported 360 casting small oval heads funnel ported to large oval, fitted with stainless valves, double springs and chrome moly retainers, aluminum roller rockers, 3/8 pushrods, melling high volume oil pump in a 8qt pan, double roller timing set, Schneider custom hydraulic cam with .540 lift, and edelbrock performer rpm intake.
