pretty awesome power numbers for the crate engine

DR525 Small Block Crate Engine | Chevrolet

this of course has to have the engine control unit and various other accessory belt mounting hardware but appears to be with its heads a good evolution for the crate engine with only a .525/.525 lift cam bringing in these numbers.... though of course it was most likely just on the engine dyno and not in a car with open exhaust.......... to get to the 525 flywheel and would be less in a car yet it is the heads working and keeping it in a good compression ratio which does make this a really good crate engine for a daily driver that has real street manners..... sure they call it drag race ready..to me its more like something more reliable..lol Just thought I would share and show this. And welcome comments about this newer crate engine.

LEGENDARY LS PERFORMANCE IN A PACKAGE THAT’S PERFECT FOR
SPEC RACING










Meet the DR525 crate engine. It’s an iconic small block LS3 6.2L with the powerful ASA camshaft, and now in a competition drag racing application. The engine comes factory sealed so you can go from the crate to the staging lanes in minimal time, with no modifications. Initially designed as the spec engine for National Muscle Car Association’s new LS Stock racing class, the DR525 is the perfect choice for spec class racing or if you just want to update your bracket-racer with an electronic fuel-injected powerhouse.

On the inside, the DR525 crate engine is built out with components designed to meet the high standards of competitive racing. The 376 cu. in. aluminum block is packed with






a sturdy reciprocating assembly that combines with LS3-type rectangular-port heads to deliver a 10.7:1 compression ratio. A high-lift, hydraulic roller camshaft delivers a whopping 0.525-inch of lift on the 2.16-inch intake valves and 0.525-inch lift on the 1.59-inch exhaust valves, enhancing the LS3’s tremendous airflow and broad torque curve.



The DR525 crate engine comes complete as a sealed unit, but you do have the choice of the Chevrolet Performance Muscle Car Oil Pan Kit (P/N 19329009) or the Gen4 F-body oil pan (P/N 19329008).

I should have said hey is it just me being the motorhead or are these numbers from the engine being identical to ours with that camshaft that actually according to the article is .25 less lift than our stock .550/.550 cam shaft for a ls3 have to have a typo for the cam shaft....... or they made 100 hp from a different ecu and heads with a tune on a lamer than stock camshaft......... I am thinking myself the "whopping" .525 lift cam shaft should have been listed as a whooping .625 camshaft!!!!!! or this set of heads are the best heads I have ever heard of for the ls3 or the performance engine control system is a much better system than our stock ecu or a combination of a couple things and it being just a engine stand rating.....?
Usually cnc job heads or performance heads are only worth 20 hp or so....... a best cam and tune with headers and CAI net you close to 540-550 flywheel so this is if it does make this h.p. with stock exhaust in a car pretty much highly unlikely or the cam is the bomb or the heads are the bomb or the control unit or combination of the tweeks in the ECU which I think is most likely just for this cam making a custom fuel map perfect etc and grabbing every ounce of power with heads because....heads are usually not worth that much.... Just my thoughts,,,,,,,,,
