All the four barrel big blocks I ever worked on back in the day from the factory only had the bathtub steel shim gasket… However as old as all this stuff is now between blocks being decked and heads surfaced good luck

Figured the guy needed a heads up….. lol

don’t sweat it 512…. If you spent any time in News & Politics you would know Baker can be an ***….

Someone got a nice car….

I can relate, back in the early 80s I worked at a foreign auto shop. The owners were involved in IMSA racing and had a DATSUN sedan. I was the engine builder and we took it to a shop in our area that had a engine dyno….as the rpm went up I started backing up…good memories.

This has to be one of the best big block street Duster builds in the country...

I know they aren’t currently available but I have zero complaints about my Schumacher headers. Plugs are easy to change, plenty of room for a mini starter, no leaks.

Low decks for the win!!!!

You need to talk to Peter Bergman, he developed and sells the coupler and is a Borgeson dealer....try the search feature here or google

Thanks The one I have that isn’t acting properly is a high flow 180 from Mancini....acts like it’s stuck open even though it appeared to work properly on the stove top

guess I will try another new thermostat...

Same issue with my Duster...stock 383, Champion 22” radiator, new high flow 180 thermostat I checked on the kitchen stove top, 7 blade fan w/no clutch, repop modified shroud. Runs 160 or so usually. The only time it will get 200+ is idling for an extended period during our blast furnace...

Bigger lash spec on the exhaust valve was probably so it could spend more time on the seat for heat transfer

The VIN is stamped (usually pretty poorly) on the top of the block in the rear on most 68 blocks

Looks good....

That is stout....congrats

My car had a 318 in it, biscuit mounts...just needed the notch for the big block oil pump

You have to cut a notch to clear the oil pump

Head chamber size will affect that 10.1 rating on those pistons .... Did the piston mfg say what size chamber that rating was arrived at?

electric to me is a no go.........you will still have 5.5 turns lock to lock unless you have the quick steering ratio idler and pitman arms, most manual boxes are worn out, another major electric load to deal with.........Borgeson looks like the way to go to me unless you have a numbers matching...

I bought a pair of E-Streets for my 383 (have not put them on yet....). I believe they only come with angle plugs...anyway my research on this site and calling Schumacher (I have them on my car already) is the angle plugs are not an issue.

I bought a built 383 from a guy that changed directions and the receipts showed he spent $1600 on the 906 heads on it...new valves, comp Springs, Teflon stem seals, very mild port clean up....etc

There was a thread on here where they had cooling problems and blocking off the hood scoop lowered the water temperature. Is your scoop sealed to the carburetor or open to the engine compartment?

Good luck on your build...I was diagnosed with Parkinson’s in October 2017..... I can relate.... I am plugging away on remodeling my house and hopefully will get a new motor in my Duster....nothing as hot as what you are building

I am building a new to me 383...the one in my car is 100% stock. I haven’t measured my piston deck height yet (I bought a motor that was already built, supposedly the block was decked). I sold the iron heads.

I just bought some 75cc e streets for my 30 over flat top 383....plugs are angled...cost less than 440 source heads as I needed to upgrade for a higher lift cam

not sure, no markings on the pump or housing and no mention of either one on the paper work I received

Sold the Victor intake and bought a Performer RPM and some E Street heads... If I ever finish my kitchen remodel I plan to get started on this project....

Nice looking test stand..... old cherry picker base?.....

my thoughts also..........
