wait.... If you have the "500hp" motor, why did your dyno sheet say 450hp?

unseenT/A

the whole story is in the thread lol the actual new dyno sheet says 501hp @6100 and 492tq @ 4900

Patriot is a very good company, I have their 725hp, 496 bbc in my 88 camaro race car. It weighs in at 4000lbs with me in it and the said I should run about 10.45. My best pass to date has been a 10.24 at 133.04 mph! tHEY HAVE BEEN VERY HELPFUL AND VERY IMPRESSED WITH HOW IT IS PERFORMIONG!

unseenT/A

Agreed the company has been very helpful and the motor is running great with no issues to report

I agree with this question every crate I have ever ordered with a dyno sheet needed no adjusting after dropping in the motor. I find it hard to believe that they dyno'd your engine

unseenT/A

Well it's possible they didn't dyno the engine at the time they shipped it to me because i do believe either the engine was a return or a reman like i said Jegs did me a huge favor by taking my other engine back.So who knows what Jegs told them to send me to save money.

Engine is still running strong just put a t56 behind it and love it even more..everything else is irrelevant at this point,i haven't had any problems besides the rocker arms,which if you read the thread they sent me new ones without a hassle.

If i could go back in time i would have pushed Jegs to the side and ordered straight from patriot's website.As it seems Jegs had alot to do with why i received an older 500hp model and not the newer dart block 450hp..

But still am happy with my purchase to this day and would do it again.

Any company with it's name tries to portray themselves as American is a totally owned off shore and then builds,machines,all their parts off shore is a deal breaker for me.First impression is kind of dishonest.Then the clincher is they forced a huge mid western dealer to eat 2/3's of his head inventory due to bad castings.

Just the same as it is everywhere else.If it sounds too good to be true...........

midias

They use Dart blocks in their engines but china castings in their heads. I think most GM and Dodge heads are cast in china. The machine and assembly work is done in American in alabama right HERE

cliff1970

they definately have dynos and use them all the time. a friend of mine owns the place and im in there pretty regular. dont believe marty would cheat anyone

1gary

There are a whole host of companies that are quality casted and machined here with tight QC procedures.

Based on what was posted.........someone tried to slip one by.

midias

Is your friend off shore like gary states or is the company American owned?

1gary

His friend is likely a contractor.I state these facts as a industry known fact not from a fan based source.To me the fact of it being a off shore company isn't as important as how that impacts the quality of the product or lack there of.It is irritating the name used through.

I strive to post facts only once and not involve myself in long debates.The rest is up to you guys to use or not.

lol, the 500 hp engine comes with roller tip rockers........ the 450 hp one had full rollers....Please post the dyno sheet that was included.

86_irocz-28

So hows it running? how many miles are on it now?

unseenT/A

Engine is still in the car and running great no issues to report, not exactly sure of the mileage but it's probably got about 15K~..

why the two piece seal?

There's nothing better than having your built by your own mechanic. I got my motor from Dyno used with 20,000 miles on it. He built himself and he's ex-professional Drag Car Driver and he knows and works/builds everything on 3rd from bumper to bumper.

i had a set of patriot stage 2 cnc ported 5.3 heads on my ls1 for awhile. those heads made less power than my stock LS6 heads i have on the car now. they looked great, but performed sub-par.

not trying to take anything away from the op, as long as his stuff runs good and he's happy, thats all that matters.

john 91 camaro

There heads are junk I've head a new set for a few couple years. I finally have the parts to put the motor together. After inspection in and out i have sent the heads out for new guides,seats actual 5 angle valve job and completely reshaped port work due to the fact the castings were never ment to hold a 2.08 1.60 valve combo. Small heads may be better but i also own and am trying to run there vortec heads and having nothing but problems with them JUNK buyer beware

1gary

Amen brother!!!.

I just want to second the opinion of junk blueprint engines. Had valve train geometry issues from day one, blow by, rediculous oil consumption( 5 qts between 2500 mile oil changes, or 1 quart every 15 passes at the strip). Always had funny bottom end noise and oil leaks everywhere. Thankfully it grenaded one month before warranty ended and they honored warranty. Got it back and sold it on cl before it ever came out of the crate and went LS with the money ( plus some). Customer service was good and very polite, just do not trust their products in the least.

unseenT/A

Just an update everybody.

Engine still running good, no problems. Installed Doug's Long Tubes over the weekend waiting to get the car back from the exhaust shop getting a new Y Fabbed up.

Patriot Performance is gone, the company went under or was sold not sure..

Can't remember how many miles are on the motor since i've lost track without a working speedo, but next summer will be the 3rd summer of it in the car.

And yes i would NEVER buy a Blueprint Engine again. lol

Wonder who got all the stock and when they will be selling off the stuff cheap?

I'd buy some patriot heads if they were cheap enough!
