Well that sucks. I need to check the pricing on Torco. Last time I checked it was 30-32 bucks a quart plus shipping. I’d pay that, but if it goes over that I may need to look at other options.
Trick flow heads how are they ?

What???, I could see you saying this if he was running a comp xe274 with 9.5 compression but no way with his combo. The trickflow heads are 190 cc street heads, kinda like cnc ported edelbrocks. Thats why some guys don't see the MAGIC improvements they think they will, they either have mild engines that don't need that much head or already have some pretty decent heads and aren't gaining a ton of flow within the lift parameters of the cam/valvetrain they have.

He doesn't know what cam he had. if the cam is close to what he's going to put in there he may not see a whole second lost at the track..

I measured the old cam and got .336 or .504 lift and the X heads were 2.02/1.60 with 78 CC. I think the trick flows and the bigger cam plus the boost in compression with the 60 CC heads will be a nice gain at the track
I have three sets. Very nice heads.
Two cars are waiting to make first passes on them.
First set are on a 394 with a flat tappet cam in my Dakota.
Second set are on a 408 with a roller cam in my Valiant wagon.
Third set are on a 360 with flat tappet cam sitting on the engine stand.
Just waiting for tracks to open.
Only report I have for now is both engines sound good and feel good driving around the neighborhood.

Does the chemtool additive have lead? Torco has both leaded and unleaded but they only advertise the unleaded. You have to ask for the leaded and not every dealer carries it.

dont think so , not sure --------I dont need the stuff myself . Might be worth a check--
Reading all your facts I would say a 1 sec gain is possible with your new combo, going from 78cc heads to 60cc could raise your comp by just over 1 point. The 3.91's and your 3500 stall will be weak though, I would up that to at least 4.30>4.56's and 28>29" tyres if you can fit them with a min 4500+ verter then it should really take off....but it'll no longer be a street/strip car if thats what it is now as most are.......just some thoughts.
I went from running 13.3@101 with a 3500 stall, .484" hyd., 750DP, small hdrs, with a stock '71 340, 3.55's/26" slicks to>
12.39@108, same block/heads but added an MP .590"sft cam, strip Dom int. 850DP, race hdrs., 4.30's/4200stall/28" slicks....3550lbs Cuda....and I only added 67hp to the motor with cam/carb/intake/hdrs which isn't a 1 sec gain in ET.

But you also know there's a difference going from 13 3 to 12 3 from 12 3 to 11 3?... In this range things start getting expeditious...

You can twist perceptions, reality won't budge
I can back this statement up first-hand. My 340-based 416 with mildly hand-ported J-heads and about 10.25 compression made right around 520 HP/535TQ on the dyno with a 750 carb that wasn't tuned as good as it could have been. I'm running 3.73 gears and she's a blast to drive!
No doubt! That’s why you see more “Basic” hot rodding Techniques and parts being used. Going for a certain goal, Time slip, can be expensive. At least you if you have a target you know what you’re shooting for. That saves a ton of time and money.

With the new information on the old cam lift then again we don't know the duration...
If you was running 12-3 I would say he's got 11 8 or 11 7 licked... But with no other changes except the heads and cam I think 11 3 is a bit of a stretch but that's just one extremely slow stroker guy's opinion... (AKA.. the slowest stroker on the Forum)...

I have access to some 4:10's and I'd be open to a new stall convertor. I had 27 inch tires on with the 3:91 gears and I wasn't even hitting 6000 crossing the stripe so I dropped to a 26 inch tire and crossing at 6200 now. This is going to be fun, I love testing and tuning. When I first started racing with this combo I was running 13.1 to 13.3. Did some tuning, super stock springs, new rpm air gap intake, 3 inch exhaust with super 44's dumped at the axle, new slicks and was hitting 12.3's consistently. Plus I learned how to drive from some cool old school racers
Stop beating yourself up.
In theory, you know how to fix this. Get busy! lol!

That all sounds great and I just want you to remember that like in post 60 things start getting a little bit exponential has now that you've made it down to the 12 3 range... Those extra seconds and tenths of a second start getting harder to get..
Not trying to be discouraging, just making sure to keep things realistic...

I hear ya J Par and I get it. The faster I want to go the more it will take in money and horsepower. I'll take what I have for now and run with it and if I get mid 11's I'm cool with it....for now!

my biggest problem is I would change the gears and the converter and everything else and never know what actually did it. It would be nice to change the heads and the cam and see if that got you somewhere and then start changing other things...I hear ya J Par and I get it.

Probably going to need a good 8” converter for low-11’s.
If looking for best ET’s, I’d be running a tire/gear combo to have the motor turning 6700-7000 thru the lights.

That will be the plan, let's see how much the heads and cam change my times and go from there.

Update, I bought Mancini 1.6 rockers to raise the lift of the cam to .624 to take better advantage of the heads. Currently waiting on the machine shop to install and degree the cam. A few weeks ago the shop was slow now they're busy which is a good thing for them since it's a small shop and one of the few around
Smart man.

How much compression are you running ?

I've calculated in the ballpark of 11.3 to 1.
I have Factory 596 heads that rate anywheres from 68 to 72 cc's... According to my research at any rate on those and I've just guessed 70cc's.. that's an icon flat top with valve reliefs, .010 above deck with a 4.040 bore... And a felpro 1008 .039 gaskets...
