‘69 2bbl 383 power adders?

Got a 68 newport custom with stock 2bbl 383 runs fine but want some more spunk. Wonderin what i could get from a 4bbl intake and carb swap along with a cam.

Also would like to know best cam selection for stock heads and springs. Accoding to casting number on heads they are 906 heads and have 2.08/1.74 valves

I don't think I would go over 50 to 75 with stock cast pistons

OK... I'll Stop.... Before someone thinks that I'm really serious... I don't think I would do it ether.
Not much to gain with the low compression of those engines. But if your looking to just upgrade some.... I would say.....
Dual plan 4 barrel intake
Holley 650 or 750 vacuum sec.
Upgrade the fuel system
Upgrade the ignition
Cam kit to your liking
set of flowmasters 2-1/2"
And hit the road again...…
Just don't race those GSXR's.....
Keep us posted.... Nice looking car in the avatar..

Well... Get it to the point where you can drive it and enjoy it a little... Do the small stuff... And then graduate to the larger projects..... Kind of have to approach it like its a stored older CBX750 Or KZ1000 or Knuckle head...Hehehehehe
I fully understand the one thing you said.... It has to STOP and STEER for sure !!!!!

Ahah yeah the fuel and brKes are priority right now. Can have a badd *** engine but wtf is it without fuel or brakes!! I do wanna mention i have restored a 85 k30 dually crewcab frame off, not. Ragging just sayin im not a total newb.
And i found out about myself during that build is that if i really care about something, i like to make it soo cleannn , not just shiny but tidy/hiden and detaild, id love to post pics but i feel thats frowned upon on a mopar site

Very nice truck, I like your attitude for the car, keep it running while improving it. With the right combination like Bob has suggested you should achieve 350 hp easy and 400 with bigger cam but with a loss in smooth driveability. When I was your age I had land yachts which we're great for road trips with the guys.

We're in Dorchester near London and are avide snowmobilers if we every get snow.

How do you think it would handle some boost? If i built a turbo setup and ran no more than say 5-7 lbs? Would my cam be way to small ? Rods hold up?

Because thn i could cruise like a normal civilized person, then let er eat in the strip when i wanna .

The fail point is the old cast pistons for any power adder, better piston and open ring gaps.

I Agree... Also a little better cam and some springs... As long as your not going to nuts with the boost... I could see an improvement....

You could step up to this type....lol

Boys from Finland Rock it !!!
