tks for taking the time to list all that. I was wondering if the BPE engine heads were already the GM Performance Vortec head even though they just list them as GM iron heads as to how they are gaining HP listed as 260 vs 210.My truck came with a Marine 5.7L with Forged Pistons and the GM performance Crank.
I used the EDL-7116 dual plane intake, a 1" tall Chaos split 2" diameter holes' TBI adapter (and the stock 5.7L TBI, for now). The adaptor allows for the upgraded larger bored TBI and a tune/chip or the Holley Sniper, later.
I have read good things about the Blue Print Heads and the aftermarket aluminum heads they sell. However, you should be aware the GM Performance Vortec Heads are much more advanced than aftermarket heads. Nobody is allowed to match the intake design of the GM Vortec heads, unless you pay an aftermarket race head machinists to build you custom heads. The GM Vortec's are in a class of their own. Especially the newer versions, which are thicker castings and better quality than the OEM versions from 1994. The intake runner is custom casting, not used by any other aftermarket head company selling "Vortec Style" heads. They call the bolt pattern "vortec", not the casting runners...
Before you make your decision, call these guys:
JASPER remanufactured engines, transmissions & differentials
JASPER provides remanufactured gas engines, diesel engines, marine engines, transmissions and more for your car, truck or boat.www.jasperengines.com
The marine version has brass freeze plugs. If you get the forged pistons and add on the GM Cast Iron performance crank and actual GM Performance Vortec heads, you might be better off in the long run. My Marine Jasper Engine did not come with heads, it was a short block.
The GM Performance engines from Mex have had customer complaints. Too many for my nerves.
Somebody WAS sending out poor quality control engines... unless this has been rectified, it bothers me greatly. I have read comments from world class custom car builders saying six or seven in a row bad. (This is not good).
At the end of it all it's the man or woman who machines and the quality of the parts.
My heads are NOT GM Performance Vortec, they are sub standard copies. They flow OK, but are not the real deal. Blue Print seems to make good stuff. Ask them if they will install GM Performance Vortec heads?
From my personal experience, Jasper makes good stuff too. Call them and get a quote for the best engine you can afford with the exact parts you want. Package deals are not usually the best option, from any vendor. Small customization, can lead to a much more reliable engine because it gets built by a different team in the factory.
I need to reread thru the spec differences to understand where the gains are coming from.
Basically, I wonder if I would really see 260HP using the old IM and TBI setup I have. If not, then I guess the differences would really be roller cam vs tappet , shipping cost is $250 for the BPE vs free for the GM performance...boiling it down then $550 to have the roller cam seems reasonable to me.
The warranty for the GM is 36months/100K and BPE is 30months/50K....which is a nonfactor really because this C30 is not used as a daily driver so I'll never put 50K miles in 30 months or probably a 100 months.
I'll look into the link for JASPER. I do have a 99' Mustang GT that just got a JASPER "prof" installed just over a year ago. It's a long story why I have this car and why its got a "new" engine.(can't relive that disaster)
Anyway, I am leaning BPE but prefer the GM performance based on my own perceptions.
