My brother was coming home from a long night of raceing and the motor went buh bye... It was a 355 with world sportsman 2 heads, edlebrock perfermor intake manifold and carb.. just the basic mild cam and not much more.. Out of no where he snapped the number 2 connecting rods and put three holes in the pan..lol... so it got towed home, i pulled the heads off and luckily the heads are ok.. so we talked for a little bit and came up with the new motor that is getting started tomorrow..

383 sb
.533/.555 cam from summit
world sportsmanll heads
domed pistons
eldlebrock performer intake
edlebrock 650 carb
3000 B&M stall converter
3.73 gears
sub frame connectors
Hooker long tubes
MSD wires

more stuff will probably come but thats it so far, should be ready in about a month in a half...

cool, but what are the advantages of dome pistons? i've always imagined flat-top was the way to go. but i'm still new to motor stuff.

They're probably a bad idea unless this beast runs on race gas, and I'm guessing it doesn't. Also, for a set compression ratio a DISH piston will make the best power- certainly not a dome.

Also, duration is more important than throwing out some lift numbers. That tells us nothing about the camshaft you have selected. I suggest you get a better carburetor and a better intake if you can swing it.

I'm thinking the cam he wants has 554/564 duration at .050, 114 lsa
(here:http://store.summitracing.com/partde...9&autoview=sku)

If your planning on running between 4k-7200, I'd recommend the following:
I'd get a higher stall, single plane intake (think victor jr), and at least a 750 carb. Those heads will be fine.
Give us more specifics on what you're planning on buying, and we'll point you in the right direction.

Also, if your not getting enough responses (and every1 just looks at the thread, but doesn't say anything) pm me, and I'll ask the guys over at nastyz28.

What goals do you have for your car to obtain? Such as daily driver or just racing?

That is not possible.

If you look at the link is shows 254/264.

That doesn't sound like a good combo at all IMHO.

i think we'll switch to dish pistons instead, thanks, but at this time the build jut got delayed due to our family friend and roomate was struck by a car last night on his ninja and might loose an eye and every bone in his face is broken..

That cam is junk, Dont get anything over a 110lsa for a sbc. I know they are cheap cams but you are leaving a lot of power by not getting a better cam,

Nate81Camaro

Yeah, it was supposed to be 254/264....obvious typo

My cam has 110 LSA (rest of specs in my sig). It's still a cheap cam, but for what you're gonna want you'll want something with alot more lift and duration.

Cam in my sig woke my truck up a ton over the Comp cam XE274 it replaced. Sounds much meaner at all rpms from idle-6200. Go with a known cam manufacturer, get a performer RPM intake, and a Holley 650 dp.

Just figured id throw this out there for the last year and a half ive been running SportsmanIIs on a 388 sbc with 13to1 domes Hbeams a steel crank with a performer rpm air gap 850 carb and a basically mild solid roller 570 576 lift with 242 244 duration at .050 and a 3000-3500 lockup converter and a 700r4 in a G body 85Cutlass to be exact and it will run every bit of 11.60s 11.70 on 28x10.50 slicks with stock 8.5 GN rear.

Nate81Camaro

Are you wanting to keep this streetable????

BsGreenZ

it will be on the streets on the weekends racing and cruising but not a DD..

Nate81Camaro

In that case, you'll be able to get away with a more radical powerplant.
