Offenhauser Dual-Port 360* Intake ~ 'Was It A Gimmick'

360, bored .030.

Heads are ported and polished 915's with 2.02 valves.

Cam is old school Purple Shaft, 284 duration .484 lift.

Used to be in the kid's Duster when my old man built the engine. 727 with 3.23 gears in an 8.75.

Now the engine sits in my M-body, a-waiting just a set of headers to go with it.

Like I said, this engine pulled hard from off idle, but pulled the hardest from 2500+ on all the way up to manually shifting the trans. Coming out of first to second the sweet spot was 6800, going from 2-3 the sweet spot was about 6200.

With the 3.23's the old man wasn't building a drag car, mind you. He had it set up for top end runs. He liked it best running 90+ mph. The car was never a dog off the line and showed a lot of BBC's and a few FE Fords the taillights in a hurry.

Like I said, what impressed me the most was the throttle response. Instantaneous. No bog, no hesitation.
