The links on page 12 is where I had problems before but now, I can get on them. Must have been on my side.
The EFI must help a great deal on mpg. I built a 428 with 10:1 compression, can is a solid flat tappet, 600 lift, 252/260 duration @ 0.50, GG- Mighty Demon carb. ect. Nothing radical. On the Mustang chassis dyno, it's 331 HP. On the Dyno Jet was something like 401 HP at the wheels. I have a 500-TKO with a 9" & 331 gears. At 60 mph the rpm is 2,000. On the Hot Rod Power Tour last year, the best I got (if I kept my foot out of it) around 16 mpg. So, with your engine having a lot more power ect., that's why it makes me think your EFI is making a vast improvement in average mpg.
I'm thinking of having Keith build me a Pond Alum. short block, his Edelbrock stage 2 heads, my Vic Jr. intake and use my 428 as a donor for the other parts. From my research in the last two months, others with the 482 have been very helpful with different combinations of cams ect. One today with a hyd. roller and about (have to look) 630 lift, 260/252, only gets 4 mpg city and 7-8 highway. That, troubles me. lol
Most of us gear heads don't give a crap about mpg but, 4 to 6 ?
From the beginning, I was just going to buy a EFI from Dynatek. What a awesome "Webber Look" that system is, just a work of art. TWM is also a great product but, I like Dynatek's appearance. I thought the apx. $6,000 was for the FE but, not so. For the BB, the price is apx. $7,000 + parts. All said & done, I can envision the system being $8,000 or so. That's a lot for a EFI but, very cool, better running, fuel mpg. ect. But, I have decided that since I've always wanted a side oiler in the car, I'm going for the alum. 427 so. If, and that's a big if,....I ever save enough cash in my toy fund, I will but the Dynatek. The problem with that is, $20,000 for a street car engine for ME,........may be crazy, and,......... my wife would KILL ME !
Do you think the EFI is helping say, 10 + better mpg ?
Anyway, what a beautiful cobra you have and the engine is fantastic. And I'll be reading about your car here and on you site. The engine sounds perfect.
Speaking of the engine video, is the "whirling" sound the EFI ? It almost sounds like a turbo.
Thank you much,
