I haven't run a bunch of different BB combos, so this is from a keyboard commando! All things being equal, I'd prefer running more cubes at lower RPM than small (stock) cubes at a higher RPM. Air and fuel volume will be equal, so you will need a good upper end either way. Converter will be required either way, and more torque will be nicer on the street than a peaky high HP/RPM motor that is soft down low.

Hi guys. I haven't posted here in a while. I have a '72 cuda. So far I have put a 4.10 dana in place and 440 drivetrain. I plan to use alot of what I already have which is a fresh 440 crank, and source heads. I am thinking some 0 deck flat tops for pump gas, have the source heads fully ported, and run a solid or solid roller. Also an at with 3500-4k stall. I do plan to run fiberglass hood and bumpers but otherwise full body and interior (3400 pounds?) With this stuff listed is 10.90s possible? HOw would you do it or what would you change?
My old Combo was a 3800lb B body on 9" slicks SS springs, 4000 stall 10", manual valve body trans, 516 heads with big valves, 590 cam and TRW 11.5-1 pistons. Ran 11.0's.
My last venture with a Buick motor I used CNC ported performer heads and a Scott Brown cam. Really surprised me how well it ran, similar combo with flat tops it ran 10.60's but would idle at 800 rpm no problem. I'd recommend Porting the heads, custom cam and/or possibly a 500" stroke kit and you should get there easily.

I prefer the ultradyne 309* 613" over the 590 cam. Had great luck with it.. I heard bullet sells these grinds now..

I was going to run the .590 but since I run 10.6 comp I called Dwayne Porter and had him spec a cam for my combo. It is actually close to the .590 but the valve timing plays an important part of it with cylinder pressure as the intake valve closing has alot to do with how much cylinder pressure it builds. And cylinder pressure has alot to do with running on pump gas. I feel I know alot about cams but I dont know what Dwayne Porter knows as he is very good and it seems every car I have seen with one of his cams runs better then I thought it should so thats one of the reasons I went with his cam. He is a pro and does this every day. His prices are very good and I wanted a custom cam speced for my combo. If you would decide to have a custom ground cam and wanted to talk with Dwayne just let me know as I have his phone #. Just an option you might consider to get the most out of your combo. There are many smart people on here but guys like Dwayne do it for a living every day and are pro's at specing a cam to a combo. Also if you do go with a solid flat tappet which I did have it nitrided as Dwanye suggested and did that to mine and also told me to run the EDM lifters which have a tiny hole on the lifter face that puts oil right on the cam lobe. Nothing wrong with the 950 carb as I only use an 850 right now. The 1-7/8 headers will do the job for you. Ron

Back in the early 90s we had a 68' Barracuda @3380# w/driver....
440 block 4.375 x 4.15
906 ported iron heads
.590 MOPAR solid cam
M1 intake gasket matched w/2in spacer
Holley 9375 1050 dominator
BME rods
About 11 static compression w/flats
2in fenderwell headers
727
9in "J" converter
4.56 Dana
SS springs w/inboard
Mopar rear shocks.....Koni SPA-1 fronts
SS Hemi style scoop
31 x 12 Firestones
Drove the wheels off the car on the street and only had about 15 runs in that trim before we switched to 440-1s, a solid roller and good headers.
Raced it on cheapo Cam 2 110 because we had a station 3 miles away that had it at the pump for $4 a gallon, so it drank that, mostly......but it would drive around on 93 pump with no issue.
In decent air at ATCO, 10.06 @135+.
Most fun car I've ever owned......cheap to build and low maintenance.
It doesn't take much to run 10.90s if your in the 550+ range and your converter and gear aren't in left field, but 3400# might be light for your car, unless you've taken some steps to shed some weight.
