3285. Its tickled 119 couple times when i still had the 727 in it. Swapped to a 904 and its only been about 1 mph down. Convertor is a bit too loose.
I am contemplating taking this 360 out and swapping out stock rods and pistons for aftermarket rods and pistons but cant seem to find a slug that gets me between12 to 1 and 13 to 1 with these 58cc eddie heads, might open up the heads some more too.
Have a 418 shortblock sitting around, but if i go that route might be needing a rearend upgrade too, and dont want to go that far..... so may sell it to pay for upgrade on my stock stroke motor. High 10’s in good air would be realistic

3285 with you in it?
At 119 that shows 426hp.

Yours is a 360 with ported RPM heads, aftermarket intake manifold and Holley HP type carb, with a .560-ish solid cam.

Now....... if you tested that on the engine dyno, back to back against my friends 350 Pontiac Stocker motor...... stock small valve heads that flow 200, .420 lift cam, stock intake and a q-jet carb...... which do you think would put up a higher number?

I have no idea. I know my motor is a pooch. Factory stock low compression shortblock. And the heads are far from fully ported. Local guy whittled on them one night after supper and was done well before before the 11 news. Then valve job at our local NAPA. 350 for the headwork
Low buck deal, but tickled how consistent and trouble free its been.
I am sure that stocker has way more attention to detail.... lol

Fast68 this exactlywhy I started this thread. I know something is not correct in the combo and only racing for a few year I'm look toward people with more experience to help guide me were I need to focus my attentions next.

Looks like I'm heading to the dyno, doing the suspension and good shocks, and I going to have the convertor freshened (as I was told it's roughly 12yrs old) the this winter.

Don, the motor does have nice attention to detail....... but you feel that some attention to detail is worth as much as ported aftermarket heads, a good intake, fancy carb, and a big cam?

Would you feel it’s reasonable to assume all your aftermarket stuff vs his stock stuff (with some attention being paid to the details) would be a wash power wise?

Frankly, if they made the same power on the dyno, that really wouldn’t be a very good endorsement for all those aftermarket parts.

Neither motor has been on the dyno, but I’d certainly be disappointed if your combo couldn’t beat those 200cfm cfm heads, stock intake, and q-jet.

However....... it does “show” it’s making about 50hp more on the moroso chart......475hp.
10.80@123 at 3350lbs.

We haven’t dynoed the 350, but there’s no way it makes 475hp.
That’s pretty close to what the 400 makes....... and the 400 has run over 4mph better than the 350.

My whole point about all of that is...... some cars make way better use of what power they have than others.

From what I’ve seen......a 10% combo isn’t at all uncommon.

Also, it’s often cheaper and easier to just “build in” some extra power when doing the motor than it is to try and figure out what’s wrong with the car.

When it’s not a “performance catagory” where how fast the car goes actually matters....... if the car runs the number you want........ but the efficiency isn’t great........ do you really care?
