Get the air in and get the exhaust out.

Back in 79, my 78 Y88 WS6/W72 TA, auto, stock ran 15 teens.
I added stock 74 head pipes into the factory resonators and tailpipes. A flex fan replaced the factory clutch fan, I opened the hood scoop and installed LR 60 radials. The car ran 14.20's in the fall of 79.

A friend had a bone stock RAIII 70 TA, 3.73 automatic, no options. We ran many times and I always pulled him by a car or more. (man it drove him crazy)

I installed a 455 right after that, but had I continued an HO or RAIII cam would have been next with a set of headers and an earlier factory intake.

The motor is an air pump, the easier you get it in and out the more power it will make.

My W72 Can Am has run a best of 15.1@91. Mods include timing, slightly fatter mixture, open scoop, and 2" dual exhaust. Race weight is 4300. No changes to the long block at all as delivered from PMD.

A couple of years ago my friend's 78 w72 4-speed ran 14.8@95 with just true duels best of 5 runs,I posted this on another t/a site and was pretty much called a liar,nice to see people aknowledge these cars made good power and could post OK times considering the relatively small cam,and low compression.

I too own a 78 w72 4-speed in '92 the PO installed a comp 268H and headers to me it pulls pretty hard,in '04 I ran it, after a couple of runs, I couldn't get it to hook, I've never ran it since.

I can only imagine what 10-1 400 must feel like.

My friend liked the way my car went so much that we just installed the same cam in his with a recurve and heddman 28150 headers,the cam REALY wakes up these engines.

Don't mean to put you all to with my rambling
