349 CI on the cheap

Ive been talking about my 349 build with Bobby - Unfo weused the wrong slugs and got limited P-V clearance, so my cam is only a smallish solid.

I finally got the combo sorted yesterday- and I think my times show the combo has potential.

Also, I did the swap from heavily ported 318 heads to STOCK 360's, and my track times prove it was worth it.

318 welded ported heads, 2.02 nailhead -
Best of 13.46, 1.91 60 ft, 99 mph.

360 smogger heads (NO porting), 1.96 tulip -
Best 13.17, 1.91 60 ft, 102.7 mph

For all the work done to the 318 heads, they were laying over in the top end, and clearly there's more in the combo if I port the smoggers.

Heres the background -

2 day - 88 deg F / 18% humidity -

With factory 360 smoggers (just a clean up - no bowl port -210 cfm?) and 1.96 tulip valves,
GM HEI ignition module,
3.9 gears , 27" tyre, on Firehawk road radials
Butchered Hi Comp slugs and 10.2:1 comp.
Comp 495 lift 282s cam -

I ran 13.17 in a 3620 lb car.

Bobby BJR - Thanks for your input on the heads - it helped convince me the potential was there...just needed releasing.

BTW - this car drove me 550 miles (One way) 5 weeks ago to visit family - :cheers:
