I have a 1969 Ford Explorer with a 360 (de stroked) big block. after some research I discovered it’s basically a 390 block. this y seires goes up to 428. been
doing research into the Cobra Jet 248 and SCJ 428. i haven’t had that much luck in finding out what i want to know besides specs and links to ebay for 428.
I would like to compare the cost of building the engine into a 428 CJ (or SCJ) compared to supercharging (and/or stroking) a 4.6 or 5.4L triton motors.
maybe even a HP comparison.
Of course, when you get into wanting to make “big power” you essentially lose your privilege to decent fuel economy. I don’t particularly forsee long
distance travels. I just would like something that will put a grin on my face when I mash the throttle. Really, an old school engine compared to modern
engines sound COMPLETELY different. There’s nothing like that old school grumble.
I had seen a NA 428 rated at 525hp (crate engine) and that’s the only specs i could see. someone else said that the superchraged version of the 5.4L Triton
are capable of 700hp (not sure about factory ratings).
Tips, Knowledge, AND OPINIONS are welcome. Thank you!!
