Results of a few changes
 

Went into the winter wanting to "beef" my engine, plans were jesel belt drive, better lifters, pushrods and a oil pan. I did swap oil pans (steel moroso to a steel moroso with a kickout)and took the timing chain off for a jesel belt drive, did a better lifter, but did not get to do pushrods (to much grinding while on engine). Decided late into doing the upgrades to do a intake swap, I've had a fall on its face issue anything past 7100 in the past and I had changed everything but intake. Here is the results



APD 598 short deck, bmf 385 heads same dyno and conditions, pretty fair A/B test.

Left side sheet is with a profiler sniper intake (fully ported)
Right side is the new sv565 with only a gasket match

Ya need to hold on a little tighter now.

Jus' bein a wiseass, but it doesn't appear that you need to go much past 7100 !

Pretty effective . .
