Wow that's fast. I hope mine can run in the 11,s that would be awesome. Here's my final build. I've talked about it before but changed a few things.
440 bored 40
Lined, squared and zero decked,
Factory LY Rods with ARP rod bolts,   crank turned
Forged Race Tec pistons @ 670 grams
Comp Hydraulic Roller 110@50 236/242 with 544 lift
Trick Flow Roller Lifters
TF 240 Heads
Smith Bros Push Rods
1.6 Mancini Roller Rockers
Holley Street Dominator
Either a QF or 850 Proform Carb
TTI 1 7/8 headers
3.91 gear and a T-56 Magnum 6-speed
Firecore distriburator And F-50 wires with a Revenator

You will certainly have plenty of power to run well into the 11's.

The big issue with std trans street cars at the track is, can you leave at a high enough rpm and still have it hook(and not break something) decent so the 60' times are low enough to get you to your target ET?

That.....and..... Can you row through the gears well enough?

When I watch street cars with sticks run at the track, those are usually the two things that will make or break the numbers you put up.

Another auto combo, circa 1990;
68 Charger R/T, 446 with trw l2355's, mild ported big valve 906's(no more than 250cfm),
Crower 248/254-110 solid cam, like .545/.555 lift, iron rockers, TM7, 850 Holley DP, 2" headers(motor dynoed at just over 500hp), TCI 10" converter, 4.10's, 28x10.5 slicks, SS springs, 3900lb race weight.
It went at least as good as 11.60's with that combo. I seem recall it going .40's with a 9" converter.

Later on, more head porting, port the intake, send the carb out, roller cam, lightweight pistons, 29.5x10.5 slicks and 4.56 gears, Cal Tracs w- split mono springs...... 10.80's.

A couple years later, B1BS heads and a bigger cam = 10.50's

Add a MP tunnel ram and 2x 750's = 10.30's(best of 10.29).

New 528 short block, bigger cam, 4.10's back in, new ATI converter = 9.90's(best of 9.84).

Add ladder bars = 9.70's

It would be interesting to overlay the costs of the baseline and each upgrade to show what speed costs.

Well we got rained out today. Ugh i was super excited to hit the track. Gonn ahoot for another day

Your head will spin..... lol.

Oh, I realize that. I've been building these things for over 30 years. But we also have a newbs come on here that throw out a shopping list of parts they put in their  build and now they are pissed that it only runs 14s.

I first met the owner of that 68 R/T in 87 or 88, at the track....... And I'm pretty sure it was his first time there with that car.
It had the stock long block, the tm7, 850 Holley, headers, and some lumpy Crane cam.
4.10's, headers opened up, and regular bias ply 60 series tires on it.
It was a 4 speed back then(original 4 speed car).

I was talking to him in the lanes and asked him about the combo........  And when I told him I figured if he could put  together a decent pass it might run a mid-13 he looked at me like I was clueless.

Well, after a few tire frying, gear missing, engine popping mid/hi-14's, he was thinking a mid-13 might not be all that bad.

We talked a bit more and it was revealed that he'd had a local speed shop recurve the distributor.

I put a timing light on it and as it turned out, all they had done was wrap the loop of the big spring tighter around the pin, so the curve was super slow. But it still had tons of travel, and the total timing at high rpm's was almost 50deg.

They had set it at like 38deg @3000rpm........ But it was still advancing way way beyond that at high rpm.

He said he was only running it about 5k, so I reset the timing to 38@5000, coached him a little on walking it out off the line, and he put together a pretty decent pass...... Right about 13.50(no more skipping).

He ended up shipping the dist to me, and I actually recurved it, told him to buy some small slicks and a smaller carb.

With just those changes and a little seat time it was running like 12.60's.

...and there is something that we never discuss but can really have a meaningful impact on the numbers, both et and mph.

You mean like watching all the stick cars go down the track with 1/2  to 3/4 second shifts? They crack me up

My distributer is the mopar dist. Made by mallory. Well i tore it apart and pinned it solid. No advance to worry about on my setup. Its full advance where it needs to be at all times. Runs better that way, and starts just fine. I also run 100 oct avgas. Runs 38 to 40 degreese. Thats where it wants to be and runs the best. Kinda a cool trick.
