over the winter my friend wrecked his 74 turino pretty bad and really doesnt have the $ to get it fixed, the body was pretty shot so its not really a loss. This means I can prob get whats left of it for pretty cheap including the good-running 351w. So from what I understand putting that drive line into my '76 I6 follows the same rules as a 302 swap? I would assume that i will also need a bigger rad to keep it all cool? the one in the turino is destroyed so I cant use that one. any in put would be apperciated, thanks
74 was a good year for 351w heads... if it had the originals. Even if you don't want to use stock heads, they definately have value. If you plan to rebuild the engine at any time in the future, remember that a W can be stroked to 393 for cheap. You are right about the swap though. The 74 351w would bolt in using all the accessory parts that it would take to use a 302. Your car is set up with 5 lugs and probably disc brakes, so you don't need much else unless you go to beefing the 351 up beyond the capabilities of the driveline. The engine will fit, even without shaving the towers, but it is much easier to maintain with the towers shaved. Good luck Dave Edit: I notice you say "driveline"... The rear will not work as bolt-in at all. The tranny is only a good deal if it is a C4. C6 or FMX both need special considerations to be any good to you.
hey thanks,i didnt mean to the rear. it probably has a stonger c4 than my 250's so ill use the turino's. dont worry I do have a 5 lug, disks front car. so what do I do for exhaust manifolds? are there headers on the market? and aim assuming the 250's rad will have a hard time keeping everything cool?
You probably will need to step up to a new v8 type radiator at least, if not an aftermarket bolt in. Your best bet with headers is one of the swap headers commonly available. They have 1.5" primary tubes, but should be least hassle. There are guys that have forced 1.625" 302 headers in by the BFH method, but once you start crushing tubes and such, you probably end up with less flow than 1.5" pipes. Then there is the Hooker 1.75" swap headers, but they need some careful trimming here and there on the car to get them in... and they are expensive. Good luck Dave
if you're not going to be running more than 500-600 horse, I'd suggest a 94 + 5.8L block. they're "roller cam ready"
i was thinking about a 351 with 302 cam and firing order just for the fun not to many people do it any more but thay will run like a scalded ape
the firing order does not matter as far as power. use what matches the cam. 351w firing order puts less stress on the front main cap is all.
There is a reason that the 351W has a different firing order than a 302. They change the firing order because of the difference in rotating mass. If you look at a 302 firing order the first 2 firing cylinders are 1 then 5. That puts 2 cylinders firing back to back on the weakist part of the engine, the front main barring. Yes it will work and yes they do run good but actually not as good as the 351 firing order. That is why the High output 302s in the Fox bodies have a different firing order that the non high output (yes a 351W firing order). The 351 firing order is actully more efficiant. You can use a 302 cam but you will decrease the life of your engine.
SBC guys have figured this out too. They have gone from standard firing order to the W firing order and Comp Cams claim it's worth 15 hp as well as spreading the load on the main webs.
