i know exactly how big it is... i worked for amazon racing for a VERY long time ive pulled a few blowers out. but if you look at the 2.8H its only about 6 inches tall and about another 6-7 for the intercooler. a 4 inch cowl should be enough to clear it id think. should be any taller then say a lightning motor which i think needs a 6" cowl to clear
Don’t take this the wrong way, but it really doesn’t matter where you worked to be quite honest, You still seem to have missed the point I was trying to make. You literally don't have the real estate in the oil galley on an OHV 302 to work with that you do an OHC engine. Yes, it requires approx a 7” cowl hood in a Fox body (at least that what was needed with MM&FF’s Project Frightning a couple years back) with a complete lightning engine, but we’re talking lightning blower and intercooler with a custom manifold on an OHV engine….not an OHC. Its gong to be considerably more than just 12 or 13” of Blower + Brick in over overall height…especially when you consider having to factor in the actual manifold itself into that equation.
Take a good look at Frightning and try to visualize what it would need to look like with the need for even more hood clearance?!?
…and this was bolted to its original 5.4L SOHC engine, with their original use of a 4” cowl hood
The OHV engine doesn’t have a deep intake galley to work with like the OHC does. You’d have to increase the intake height and therefore the brick and blower height considerably just to elevate the intercooler brick high enough in the galley to keep it from sitting on top of lifter bosses. On top of than, you’ve got 16-pushrods in close proximity also in the way, which requires even more elevation still. You’d actually be further ahead with a 351W as a custom set up than you would a 302W, since you’ve got an extra 1-2” of width to work with.
Here’s another example of a 6-71 on a 351W intake.
Even if you disregard the top feed carb inlet, the physical size of the 671 isn’t more than about 2-3” taller than the 2.8L H. Take into account that even with the difference in height, the picture blow has zero provision for another 7” of intercooler brick and increased manifold depth and there’s no way you’re getting that thing under a 4” cowl hood. Not in this lifetime!
No, I stand by my original statement of at least 10” of cowl hood needed to make it work.
