I used the engine as a kicker on that Plymouth. Didn't have any issues til the last run (Norwalk fall show). Broke a bolt off in the engine and broke a chunk off the block. Mount was a little hokey though cause it sat in that car a little weird. Was using the holes where the ps bracket would be.

I'm not talking about anyone in general besides myself. Lol I've done it and I've regretted it.

May I also add. this is for full size rwd cars.. I've ran one bone stock w body so I know nothing about Compact or midsize builds I've definitely pressurized some things on rwd compacts. I think it's pretty much a must to press the engine into the firewall and weld it in (with the front end hanging). I think with how much unibody cars flex, pressurizing them is not only fairly easy but can also be a very effective way of making them harder. People have thought I am crazy, but even without being able to run an engine protector I push the back of the head into the dash bar. I feel like compact cars aren't hard enough to rip my 10 head studs out... the car will fold around the engine before I hurt anything. I've also put pressure from the sway bar on my pulley protector, but I think I've over done that, because I've broken a couple of them during the derby. lol I've never built a w body, but I'm guessing guys that are doing serious builds on them are probably finding ways to pressurize the sub. Ive done it a couple times but it depends a lot on the rules imo. The problem is the frame rails that the sub attaches to is a major weak point. Unless your running full weld, putting the pressure from the sub to the rails isn't a good idea. Few shows around me allow you to add two body mounts and that's when it gets interesting to me. If you can't address those a non-pressured sub will outlast your rails anyway. Jmo

For rwd weld compacts I ran a 2.3 with a full cradle I'd just set the motor in and porta power it into the firewall till it started to bow in some, same with the tank protector. My mustangs bent under the driver's seat every time lol it did take a few shows for it to happen tho😎

Good to see the big hush hush stuff coming out. So how about a little more insight.
Have worked on 03s and building another. Weld a temporary transmission crossmember in first. Removed package tray, run hump plates on inside of rails. Remove about an inch out or rear package tray, pull rear frame rails in to package tray with bend point being temporary crossmember. Weld package tray back in. Pressure more once welded in rear then weld bumper on. Has a tendency to pull rear rails inward when rolling. Then weld engine crossmember in, remove temporary crossmember, pull rails in front of crossmember inwards. Tilt and take vertical bends in front of crossmember out. Then weld in a arched forward crossmember in to where temporary crossmember was. Pressure engine and transmission back until its about 1/2 way, then put cage in and weld a down bar to where the frame is pushing out with gussets. Then finish pushing in engine and transmission until crossmember is almost straight. The body should be loose while this is happening. Then pull the body with body bolts tight around the transmission brace.
Remember when demo used to be simple? Lol

Style of driving, a lot of guys don’t know these tricks, bumper has a lot to do with it, plus everyone has their own little tricks

if guys r doing all this $hit ,preloading frame,pushing motor back ect and no protectors. please explain to me on a ford that has 5 plus hard runs and in the top 3 every feature and not bend ? Tony, it's easier than you think. Look at the cars, most of them have clean bodies. In this case, it's not "pressuring the motor and trans", its pressuring the frame using the body. Plus I know for a fact that a couple of those cars were tilted.

You can plate fords in several places up front when you cut the face of frame out, put thicker plate there, weld, grind, and paint. Lots of hidden stuff

Pipe the rockers... yikes. There are guys that do it....I'm not one lol I dont have the patience. Pipe the rockers, separate the fenders and plate the insides, plating the boxes, theres a lot of things that's easy to get away with.

Improse, I think what it comes down to is those guys have built dozens of Fords and with a crap ton of trial and error and research they have them down to a science. Is there a little extra here or there? Maybe. You've got to remember as well that I'm sure after the first time they run them they are getting fix-it plates.
Also, we may have never ran a fullsize mopar ect, but with running rwd compacts, yes, we fully understand what the rockers and floor can do. strengthening the middle of the car depending on the car and build can do more than most understand.
How ever I don't think piping rockers would mean a hole hell of a lot on a mild weld Ford. But you would have to ask the guys half your age that are dominate in that class.

I guess that’s how I am, the low key grey area stuff I won’t tell people unless specifically asked but if I am I’m not affriad to tell, I did a whole step by step build thread so everyone could see what I did.

So if I was building a car with no protectors, lets say a 62 imperial... LOL. What do you mean by using the body to pressure the frame? I plan on running a solid lower cradle with a pulley protector but probably isn't wise to but it to the firewall with a trans protector. I have to run a stock cross member as well.
