Caseyrhe 650 Report post Posted July 23, 2019 Yes, will need the mtr mount perch brackets for a big block, they look the same from a distance, but are indeed different. You will also need to start customizing wrenches and shrinking your hands to fit in the limited work spaces. Power steering hose support bracket is also different 1 1 mustangstofear and RPM reacted to this Quote Share this post Link to post Share on other sites

Mach1 Driver 560 Report post Posted July 23, 2019 I was just at my monthly Mustang club meeting over the weekend and one of the guys brought his 69 GT500, which of course is a 428 Cobra Jet. He says he has to take the export brace off to change the plugs. He was complaining about too little radiator for too big an engine. He added an electric fan for the main radiator and added a separate trans cooler with its own fan. Another guy showed up with his 69 GT350 which is a 351W. Imagine that, two Shelbys in the same club! It was originally ordered by Hertz to become a rental car, but their insurance changed and they never took delivery so the dealer drove it for a year and then sold it to our club member. He would routinely run away from the police until after five such instances they figured out where he lived. Quote Share this post Link to post Share on other sites
Caseyrhe 650 Report post Posted July 23, 2019 You can change the plugs without removing the export brace, just need a swivel head ratchet. I feel the hardest part is getting the plug wires off and on. Over heating can be an issue on a block bored .60 over, but with the 4 core radiator and therm, my temp usually runs around 180-190 in the Texas heat.

Rsanter 152 Report post Posted August 21, 2019 First we have to ask why you want to swap? if you want more HP then go with a stroker. If you want the look of an FE engine....well there is no replacement Quote Share this post Link to post Share on other sites
Vicfreg 771 Report post Posted August 27, 2019 I chose the Windsor based 393 stroker option, it will have plenty of power for me. Quote Share this post Link to post Share on other sites
