The engine in my MK3.1 came from my donor 88 Mustang. The Mustang was built to be a hot rod by a guy I never got to meet for a kid that had limited resources. The kid that had the Mustang was out of a job, out of money, living at home with lots of parental pressure to get rid of the Mustang. He ran an ad and made me a good price on the car.
A few years later I had a local performance shop go thru the engine. He noted the 302 HO block was punched and stroked to 347 with a reasonably strong cam. etc. It had good internals and he thought it would last me a long time. He did note some issue with the way the engine was balanced (unmatched flywheel and balancer I think) and fixed that. The engine runs pretty strong and makes the Cobra scoot along.
I was encouraged by this site during the Cobra build to swap the single plane intake with a dual plane intake. Good advice which I ignored. The engine had what turned out to be a junk Holley that the above performance guy replaced with the QuickFuel 680 with vacuum secondaries. The Cobra has an automatic trans with a 3:08 rear end. It was too violent for me with the 355 and shift kit.
So here I am many years later dealing with starting problems after a long winter sit (another post is open on this) wondering if I should consider making a switch to a dual plane intake while I am working on my starting and running problems or leave things alone. I'm doing very little driving now. I think I drove like 300 miles last year.
Any good suggestions one way or the other will be appreciated. Jim
