who has the fastest 318 ?!!!

The OP bailed on the teener? Ha-ha.

I'm just guessing but I'd say people that have a teener do so because of budget, myself included.

I have 72 dart swinger that came with a 318. I was just going to freshen up the top end but screwed up the bore with a ridge reemer. Now planning a full rebuild on the 318.
I have a 97 Magnum 360 in my wrecked truck, I also have a 69 340 block only.
Since I already ported the 318 heads and had them rebuilt, the 318 will take the least amount of money to get this car on the road.

The 340 will be saved for a 69 model car, if I can find one I like and can afford. The 360 may go in the dart later on as money permits. Stroke the 360 and keep the efi.

But for now it's the teener that will be doing giggle duty. It will be a fun car but ain't going to set any records, fun is the primary focus, V8 sound. Speed will come later. Beats driving a civic.
