![]() ![]() On a stock bottom end, the pistons are going to be a limiting factor. Ford added the holes as the years progressed, and they didn’t take any away. Basically the run down is 1998-2000 works in all year models that have the 4.0, then the 1995-1997 fit everything up to that point and so on. You can use a late model 4.0 in a early model truck, say 1990-up. In other words, there’s not enough holes in the block to bolt up the motor mount on the later model trucks. 030 overbore safely.Īlso, you can’t use an early 1990-1994 model block in a 1995-2000 truck, because they didn’t have the casting for the motor mounts from the later model trucks in the side of the block. The later 00 blocks were made from a different material, weren’t as strong, and could only hold a. The 4.0 has a 3.952 bore standard, and as tempting as it may sound to do a 4.00 bore and use just about any standard off the shelf Forged piston, ONLY the 1990-1994 blocks will safely hold a. Remember this mainly in things like custom turbo applications and turbo selection, you want to size it for full boost around 2500-3000 rpm’s to get a full power range from it, same thing with Torque converter selection. My engine with all of its airflow mods makes peak power at 4600 rpm’s, and that’s with the Comp Cams 49-422-8 cam. ![]() ![]() Most make there max power around 4600-5000 rpm’s. One major deal with these engines is the Airflow and RPM’s. It has rail type rockers that I used to have Billet aluminum rocker arms made for it, but stopped after quality control and truly never selling more then (8) kits total. ![]() The OHV engine is a Torque monster that is based off the old FE engine line, like the 390, 427 and 428. Naturally aspirated it makes 196 rwhp and 254 rwtq. My truck makes 286rwhp and 391 rwtq on a 125 shot (Nitrous). Most with well built engines and ported heads make around 250-275 rwhp. To give you a bit of perspective I only know of one OHV 4.0 like ours that has made over 300 rwhp (Rear Wheel Horsepower) and it has a turbo on it. I know I could make it work, but it would take me a while to figure out, and I want it to look good still.The limits of the OHV are more so caused by the poor flow limits of the stock heads and the camshafts. I plan to do a power window and lock upgrade in the future, and was considering putting the switches where the rear climate controls are now on the console to use the space and not have to change door panels if that's even possible with swapping to powered windows. Ive added a picture of the console in question, if anyone has any tips, advice, tricks, or hacks to make this work it would be very appreciated. I also noticed my stock sun visors are slightly too long for it to fit, are there other visors that would fit, or a way to modify my existing ones? Mainly wanted it for the extra lights and a storage space for my sunglasses.ĭoes anyone know if I can make this work? I put the mounting bracket up just to see, it only has a small gap about in the middle. I was trying to get one from a 99, but they didn't have the right models. I recently acquired the over head console from an 05 Explorer from a junk yard while getting other parts I needed for my 99 Ranger XLT. ![]()
