mav and the motor

What would be the cheapest way to replace the stock 250 i6 motor from a 1975 ford maverick 4dr with a 500-600 hp motor and what all modifications would need to be made. I have already thought out the suspension and exhaust all i need is the motor info. Would a dss racing 331 be better then a newgen supercharged cobra motor. Will either of them fit reasonably well as far as the walls go, the hood is not an issue it can be modified. What transmission would be good for this application?

The cheapest way is usually to buy one from someone who has already done it... [img]/phpBB/images/smiles/icon_spin.gif[/img] [img]/phpBB/images/smiles/icon_spin.gif[/img]

That's the only inexpensive way you can build a ford.... [img]/phpBB/images/smiles/icon_wink.gif[/img]

Well, if you must have that much power, you're going to be limited..basically by the design of the front end (shock towers!). The newer modular engines definetly won't fit in there. The 351w fits, but headers will have to be custom made, engine mounts must be raised slightly and notching the shock towers would be almost mandatory. A 351c fits...but again, headers and plug changes will be a bear. Any 289,302 engine bolts in...without a lot of problems. After all, they came with 302's from the factory (well, some of them did). Making that kind of power from a stock iron 302 block will be about like playing russian roulette. It might last 5 years, it might last 5 seconds who knows. Trust me, I've tried almost everything to get that much power (and be reliable) in a Maverick.

Years ago, I was playing around with my '74 which I originally installed a mild 302 and C4. It was respectable, but nothing to write home about...probalby mid 12's in the 1/4 (never ran it). I was bored and I had an old turbocharger out back....and I later found out that it was nearly the perfect junkyard turbo for a 302 engine. I made my own headers (one side was a stock 88300 shorty, the other side was a home-made log manifold), down pipe, 3" exhaust out the back, plumbed the compressor discharge tube to the home-made carb hat, and boost-referenced the stock style fuel pump. Boy was it a blast to drive! Later on, I put a Deltagate Racegate on it to control the power...and kept it down around 6 psi so I could run it on pump fuel. BUT the couple times I did run it at the race track, it showed a ton of potential. First time, the darn boost reference tube came off of the fuel pump and it went lean...burned a couple plugs. I caught it before it did any damage. Last time I ran it, all went well...left the line at about 5 psi and when I hit the throttle, it went to about 16 which is where I had the wastegate set to....went 1.51 in the 60' on drag slicks but the transmission didn't like it and started slipping...aborted run. Mind you, I was running 110 race fuel.

Turbo or nitrous would be the simplest and probably cheapest way to do what you're wanting. That, or put the Mustang II front suspension in there and put a 557" BBF up front....then 500 HP would be simple. But, M2 swaps arent cheap...and are a lot of work.
