Identification on used Mopar Crate 360
I can't say I know a lot about the Magnum versions of Mopar's crate engines because I ran the original LA head 360/300hp. They also had the 360/360hp LA version which basically had bigger valves, .100 more lift and a single plane. All the small blocks after that were Magnum headed. Not sure about the aluminum head versions. But any engine - the bigger the cam, carb, heads/valves, etc., the better it responds to more converter & gear. The trick is to balance/orchestrate the combination of parts to make the best "music" for the application - street, strip or dual purpose. If one "instrument is "off", then the "music" won't sound right. (Be optimized.)
I do have to correct Rumble because while I did test the Weiand Stealth for a short time, it was not faster than the Holley Strip Dominator on my particular combination. But I did have a converter that actually flashed to between 4900 and 5400, depending on weather and "tune", 4.86 gears with 30" tall Hoosier radial slicks and shifted just below 7,000. The dual plane Weiand picked up a little ET (.05+) by jetting about 2 #'s bigger on the deeper plenum side, but the Holley was still faster. I don't know if an Edelbrock RPM or other dual planes would respond the same way to stagger jetting.
The crates were designed to work on the street so while my IHRA "Stock" engine had to follow the same basic specs, the cam (stock lift but steep ramps & lots of duration.), lifters, rings, blueprinting etc. provided for a significant power increase. My best was 11.14 @ 117+ & 6.99 in the 1/8 mile with a best of 1.47 60' times.....all at 3,540+ lbs footbraking a 904 w/2.74 low gear. NHRA Stockers are even more "refined".
It's worth noting that while the Holley Strip Dominator had a much higher RPM range than a dual plane and I shifted well before the "peak" of its range, the engine was almost never below 5000 rpm. I staged around 3,000 rpm and launched from that. The Holley also has a shallower plenum than a Victor which I thought would work better for me. I figured the Victor would be too much. I never tested one but others weren't impressed. But each combo and approach will be different.
