Had a 302 coupe and decided to put in a 351W(with a little extra displacement-for insurance). Skipping the engine details for the swap details, here is what I dealt with:Engine swap headers - required especially for power steering cars. Most expensive part for the swap. $100-$350 NEW motor mounts - too much torque busted the stock ones and twisted my engine in the chassis. Not good. and scary because the throttle bound up and I had to turn the key off while sliding sideways in my own smoke cloud.  $40 Beware of the Vic Jr intake - you will NOT get your hood on with any drop base air cleaner. I don't know for sure, but RPM intake should fit with a drop base unit. Drop base unit $35 Bigger radiator - more CID makes more heat. I had an old copper/brass 2 core and got a Griffin aluminum monster. $200 Smoking the crap out of all rice burners and a serious majority of cars driven on the street - PRICELESS.... Additional info: I put in a performance C4 tranny and kept my limited slip 2.79 rear. 2000 RPM @ 65 with enough torque to break traction in second gear. This is not necessary, but someone will ask what tranny I used. Also swapped the points for a Duraspark. Would have been happier with MSD, oh well, I'm young and have time. I know this isn't specifically swap related, but I hate points. $35 at scrapyard including harness and coil. All in all, the swap was very simple and except for the $3500 stroker kit, it was cheap too. Talk about torque. I smoked a Z28 so bad I thought he slowed down for the cops. His car sounded pretty bad too. But after the 1/8 mile impromptu drag race, I beat him by about 10 car lengths. Lined up twice more and he was just plain amazed. No timeslips yet, but I estimate I have a 12 second car on street tires. I need frame ties before I end up busting something. The 351 is my favorite engine of all time. the blocks are so solid and the bores and mains are always straight. Not like the chebby 350 where you gotta get a small base cam just to get 383 cubes. And chebby smallblocks are weaker. Yeah, I'm geeked. I've been wanting this since 1987 but been too broke to finish it. but I ramble...

I like 68 coupes with 351W's! Sounds just like mine except I've got a 5 speed.The RPM does fit, and I don't even have a drop base air cleaner.

JT, did you go to ennis? They had a bullit parade with over 60 bullets, then they lined them up in the parking lot in the pit area and mm&ff took pics.We should start some kind of gang of 68 coupes with 351W's. ------------------

Wow, thanks a lot for the info MustangzRule. What Motor Mounts did you pick up? Oh yea, I'm planning on dropping a RPM Air-Gap Manifold in there, already have the drop base air cleaner. You smoked a Z28 with 2.79 gears? Mine should really move then with my 3.55's.P.S I already have the big 3-core HD Radiator since my beefed up 289 is/was giving me heating problems. Hey Stang351, I'm with that idea about having a 351W's with '68 Coupe's Club  [This message has been edited by ice'68 (edited 09-25-2002).]

While we're on the Z28 subject, I've had 2 of them and a Trans Am (All 93-97) back off from me. What gives? These are the cars that I'm gauging my cars performance off of, and I can't get one to race to see how I do?And I had a new SS do a ricer fly by that pissed me off so much. He wouldn't stop beside me and let us go with a fair race. Words can not express my anger!! ------------------

I used replacement mounts from carparts.com
And add a torque strap for insurance.

That torque strap sounds like a good idea. I bought regular old motor mounts from the parts store, for a 302, but the windsor moves a little too much for my comfort when I rev.------------------

I have been thinking about a 351W in the 68, thanks for all the info. So most of you guys run an 8 inch rear end?Also where did you find a griffen aluminum radiator for 200 bucks? I think i will play with the 289 for a while but its nice info, good to hear that you have fulfilled an ambition. ------------------

I priced a Torque Strap from Jegs at about $105 
Jegs also lists a Mid-Mount plate for about $55, would that be better?

The last torque strap I used I made from a large turnbuckle. I fabricated a couple of mounting tabs from scrap metal and brazed the loop on the turnbuckle ends so that it would not yield. It looked real nice and cost less than $10.00.Make your own torque strap its easy, just use your imagination. There are lots of ways to do it. A mid plate is a plate sandwiched between the block and the bellhousing with ears that rest on the frame. In order to install it you need to adjust the bellhousing to block to compensate for the mid plate thickness and then weld some tabs to the frame so that the ears can be solidly attached. It is a lot more work than making a torque strap. John

Griffin 29" radiator $198 4 years ago from Summit. They probably jacked the price up because of the terrorism thing. I have no idea how aluminum radiators relate to terrorism, but it seems everybody is using it as an excuse to jack up prices. It's a nice radiator.

A "plate" to my understanding is a sheet of aluminum that goes between the block and bellhousing which then bolts to the chassis. It will make the engine stiff and all torque will be transmitted to the frame. You will get a rougher riding car from engine vibration. It si definately stronger and that price is too good to be true if you ask me. I'v seen them starting at $150 typically.

How much did your Torque Strap cost and where did you acquire it from? Or did you fabricate it your self?

I can't tell you anything about this swap but I can tell you a Mid-plate is primarily designed for tube or 2x3 frame rail race cars. If you want pics of how a mid-plate looks mounted I can send you pics of mine. If I were you I'd go with the torque strap. Get a piece of 4 or 6 inch flat bar and make a bracket to bolt to the passenger head bolts ( the ones in the front for the accesories ) then weld a piece of angle to that, make it 45 degrees towards the stock frame rail. Fit a small piece of angle over the fram rail and drill some holes through it and through the frame. Now weld the angle coming from the head to the angle bolted onto the frame rail. You now have a NON adjustable torque strap. The turnbuckle type would be adjustable. Be sure to make it removable at the frame. You don't want to fight this thing later when you try to remove the engine. Good Luck

I?ve used different brands of 302 or 69-70 351W headers in the past to do the swap with no problems with PS. What problems did you encounter with power steering?

I got the cheap Summit $100 engine swap headers and the driver side collector had less than 1/8 inch clearance from the PS piston and bracket. Engine twist would cause them to rub under accel, and I removed my PS setup until I can relocate, replace, or bend the crap out of the header.

So, no one sells Torque Straps? I'm not that good at fabricating stuff and welding
