99.7 in 2nd.  Might have hit 130 if I had another 1/4 mile

Well heres an update on my 343.
Its in a 71 Javelin, shorty headers, full quiet exhaust with 2" tail pipes, 2.87 gears and a trac loc and Cooper Cobra 60's.
I went to the drag strip with it. My freind bet me $20 bucks I can't make the 13's.
My 1st run was 13.87 and the fastest was 13.64 all from the little 343.
Mines on the left, Phil Hansons on the right.

It’s about balance - avoid extremes, in life and cars. A rumpity-rump car that bucks at speeds less than 35 MPH and gets 3 MPG while being loud as he!! gets really old, really quick. If you’re after sub-11’s in the quarter, okay. 

For a ‘street’ car (and I get there’s a difference of opinion in what that means), a good running/idling engine with crisp throttle response and low-end torque that pushes you back in your seat while you can still hear the radio is a wonderful thing and a joy to drive. 

However, like everything else in life, it’s extremely subjective.

Just me. I get it about performance.    But in my experience performance and gas mileage doesnt mix. If you want fuel economy  go buy a 4 cyl car.  I get 35 mpg on a Honda civic.

I weighed my new pistons and rods, 192 grams lighter than stock.
Also I have a nice Torker I welded up heat crossover and an Offenhauser 360 not sure which I'm gonna use.
I'm using Edlebrock shorty headers, I removed the small exit flanges and welded on 3" mandrel bent pipe I ran an 11.26 with these in my rambler.
650 Summit carb.
Internally balanced.
Later rocker bridge heads converted to screw in stud.
I port matched intakes and cleaned up the exhaust ports, polished up the pockets.
I tried not to change the shape as I don't have a flow bench.
You guys think it will make 350 hp

Just manual. They are all rebuilt and have had to panic stop twice last summer and did just fine.
