Are you sure about the compression? If you have a 77-93 Windsor block the dish is only about .10 designed to produce 8.2 to 1 compression with 69cc chambered D78 heads. With AFR heads (58cc) , you should have compression in the mid 9's. Those are huge injectors. I ran 24's with my 351 and it still ran rich -and that car ran 11's. Your cam is tiny but you are still leaving a lot on the table with your combo. You have good heads, something doesn't add-up. What is the best mph you've run?
It's a 74 block so, yes, you have .26 dished pistons and very low compression. The best way to overcome the low compression is to spin the thing at higher rpm, but your small cam and long runner intake keep that from being effective. The injectors are too big but I wouldn't spend the money for smaller ones. You have an odd aggregate of parts. I see no cheap and easy solution. You need some compression, or a turbo.
Agreed
Except I would use a roots or twin screw blower, you will have a tough time getting a decent turbo to spool well with that combo.
Why didn’t you build it with a decent cam and compression? You could have just rocked a mostly stock 302 and gone faster…
I still think it is a band aid on a broken elbow, but be very careful with your turbo selection…
How fast do you want this car to be?
