Here's another what will she run, for you.

13.6-13.7

Put a better intake, carb and some more converter in it and I bet it could run high 12's.

Hypermites build from another thread:
Combo is, .060 over 318, home ported 360 "J" heads, stock valves, Eddy RPM intake w/Holley 650 dp. Comp 1.5 roller rockers, MP. 280-.474 cam. Hedman headers w/2-1/2 pipes & flowmasters. 9 to 1 cast mopar pistons, stock rods & crank, windage tray, 904 tf, w/Trans-go stage II valve body, 3.91 sg 8.75.

Hypermite has, IMO, a better intake and carb on his car. That's probably good for 25+ HP over the 625avs and performer intake. Better cam too, that won't be as soft on the bottom. The 474 outperforms the 508 in almost ever part of the RPM range except the last 500-800 or so. 474 is a much better cam for a hot 318.

You know I am taking notes for when this thing need freshening up, right? :-D

ran a similar combo in a 72 duster. the teen ran 9.20 out of the box and tuned to a respectable 8.90. at 8.90 i was competitive with all the stock late model z28s with 350s in them. made for some fun racing.this was at the 1/8 in sealy.

That is about a 13.9 the calculators say. Very respectable! I remember when we hit low 14's in the dart. Tammy was so excited we were actually beating the 5.slows and the crapmaros.

This is my 21 year old son's first Mopar and this is going to be the perfect project engine for him. When we tear it apart in a year or two I am sure we will implement a lot of these ideas.

For now this will do him just fine. He has an Army buddy with a Mustang that just ran a 14.4. He just wants to stay a little ahead of him and put a hundred passes on it or so to get some seat time. When we tear it apart we will be changing some parts and he will be able to tell first hand the difference between just throwing some spare parts together and a well thought out combo. I think this will be a great learning experience for him.
He showed up last night as a surprise and we worked on it till around 6 this morning. That was a pleasant surprise.
I am just taking a break and I will probably go work on it some more before I go to bed.:-D
