Thread: Making A Small Block 350 As Fast As It Can Be

Tweet

I just want to have one of the fastest small blocks around and want to know why some old man tells me . . .

Those kind of comments result in "some old man" NOT telling you what he's learned in the last 20 or 30 years of engine work - which is probably longer than you've been alive - and letting you build a boat anchor on your own.

For what you are trying to do flat tops ,or dish would be just fine.Use performance parts ,and you can add a power adder like nitrous.

Nitrous likes lower compression, you could use it with higher compression but it is more effecient with lower compresion.

Well,you come off older than 43 or is that wiser?Either way I guess I was wrong again.

well i pick up tools off the floor when i was 3 ok it was 5 for my dear dad when he work on his 23T B alter with a392 hemi in it

This is one of the reasons I love this site

I would have replied earlier but it was time for my nap! You guys should be glad to learn that you are not old, you are in your prime! It is not going to get any better after 50. Here is a set of dyno curves from Comp cams if the original guy who started this thread is still listening.

http://www.compcams.com/Technical/DynoSheets/

These curves show the cross over of Torque and HP at 5252 rpm nicely and they all seem to be for a standardized overbored 350. I don't see a 383 in the list. That said, I note that even with a roller cam and long duration,the 350 displacement does not reach the 450 HP mark so as Eric says the build up should be based on a 383.

The 383 in my coupe dynoed at 450 hp and 468 ft. lbs. of torque. It is a friggin' rocket in a 2600 lb. car. Here is what I used to build it:

Eagle cast steel crank, SRP forged flat top pistons, Eagle SIR I-beam rods;
AFR 190 heads with 68 cc chambers (10.6:1 static compression/8.46 DCR;
CompCams 280 Magnum hydraulic cam ( .480/.480 and 230/230 @ .050);
Edelbrock RPM intake with an Edelbrock 750 carb; CompCams Pro Magnum roller rockers; MSD distributor.

Nice lope but very streetable with a 2400 stall converter. With a roller cam, it could easily have made 500 hp, but that would have been overkill on my application, so I didn't spend the extra $ on a roller.
