what are everybodys thoughts on the 410hp RPM Creat Motor

 

As far as CRATE motors in general go, I would stay away from them. If you've paid any attention to this forum recently you'll notice that many of the companies that market crate motors seem to be in the habit of promising more than they're really willing or able to deliver, and YOU wind up holding the bag for TWO engine changes rather than one at the very least, and we'll have to spend the next six or eight weeks listening to you complaining to us about why you got oil in your water or water in your oil or why it overheats or why your cam got ground to a stump or why your oil pan has a rod sticking out the side. Edelbrock, however, is a different story- they are a HUGE company that has the resources to produce crate motors with a level of quality control that would be necessary for them to maintain their very good reputation, so I doubt very much that they would knowingly market the kind of crap that so many of these other fly-by-night ebay/magazine vendors put out there. Ditto for GM. If either one of them sells a junk motor to the wrong guy (i.e., one who's aware of how deep their pockets are) the resulting legal haggling can easily cost them a lot more than just the cost of building one motor. These ebay dudes just close their doors and reopen under another name a few weeks later....

 

well thanks but i am not buying the creat motor i am using the rpm top end kit but i have heard that edelbrock overstates their hp and tq numbers. So i want to know about the rpm motor or top end kit not creat motors in gerneal. But thanks anyway

 

Edlebrock CRATE motors are IMO way way way overpriced. You can find a similar HP motor from a good company without having to pay extra for the name.

 

I would pay the extra because, they are Trusted and you know its Made in the usa

 

I have the complete Performer Edelbrock and it is good quality. Some have had the heads ported but it depends what you plan for the motor. For me I wanted reliability and decent performance.

 

I am running the complete 539 hp Performer RPM package on my big block with the addition of the pro-flo EFI. I duplicated the test motor including the same pistons, rings, bearings, and machine work.

I like the fact they take the guess work out of the application and you have a pretty good idea of what you will get on the other end. I do however believe they overstate HP numbers, so you have to take that with a grain of salt and just figure you are in that ballpark.

We did a complete small block 425 hp Performer PRM on my buddies 350 a number of years ago. It was a beast. The tech folks at Edelbrock are very easy to work with...especially when you are working with all of their stuff. In other words, they know how to help you dial it right in vs. a mix-matched mystery motor with all sorts of heads/cams/intakes...etc.

As far as crate motors go, I just got my 330 hp GM performance crate motor last Friday for my latest project. I am installing a Pro-Flo EFI on top. Man...the engine looks great and it is backed up by non other than the General. Can't beat that! The price is sweet too considering what it would have cost to build a "myster" motor from scratch.

Good luck in your decision!

 

Hey Chris,

Any chance we could get you to do a "blow-by-blow" on the Edelbrock Pro-Flo EFI install? It's something I've been considering for a while but would like to know more about the install/tuning, etc. before I drop that many $$$$.

(Sorry for the hi-jack?!?!?)

And I'm also running a bunch of Edelbrock Performer goodies on my small block. The cam, alum heads, intake, water pump, fuel pump... all Edelbrock. The few problems/questions I've had have been answered within 24 hours (via email) by their tech line.

As has been said in this thread before... GM crates and Edelbrock crates have serious corporate backing... and yes, you do pay for it... but then again (yep, here it comes) "you get what you pay for."

I'd rather have it right the first time than get nickeled and dimed trying to set straight what was a short coming by a short sighted engine builder. If you've got an aquaintance that builds good stuff locally, go for it... if not, crates from the big guys are a reliable, well researched (if somewhat expensive) way to go.

As far as the EFI installs, I find them pretty easy in general. You have to make sure that the manifold will bolt to the heads you are currently using. The problem that may exist is the angle of the bolt holes in the manifold and the heads. The perimeter bolt heads and center bolt heads have different manifold bolt angles. Normally you will need use center bolt heads for an EFI manifold. However, I altered a few EFI manifolds be machining the bolt holes on the manifold to the correct angle for the perimiter bolt heads.

I'm not 100% sure if this is a concern with the Pro-Flo design but it is a something to keep note of.

Now as far as tuning goes, I have never been able to tune an EFI system 100% correctly on the street. Don't get me wrong I have been able to get these types of systems to run good by street tuning, but on the dyno I can get them running great! Normally we get a min of 50 exrta hp to the rear wheels on the dyno.

Just some food for thought.

cool thanks for the replys my thing is i already have the RPM cam installed and i am still up in the air if i want to change it out or not. If i change the cam im going with vortec head setup, but if i keep the RPM cam im going with the RPM Top End Setup. So what do you all think of the RPM Cam its 234/244 @.050 with .488/.510 lift

 

It is really easy.

The C3 has a natural spot on the firewall to the passenger side of the wiper motor and to the driver side of the heater or a/c box to punch out and run the computer harness. The intake bolts right on like any normal intake. You have to make sure you get the right intake for your heads. In this case I am running some vortec heads and it is a matching RPM EFI vortec manifold.

You convert your distributor by removing all the internals and replacing with the parts that come from Edelbrock. You mount the computer on the passenger side dash. You hook up the power and ground wires. You run the fuel pump wires to the rear of the car and run the fresh fuel line provided by Edelbrock. You mount the fuel pump in the rear on the last cross member.

While you are doing this you will have sent off for the base calibration chip that matches your engine combo. By the time it comes back everything will be installed.

There is a simple "getting started" section in your instructions for setting the base timing and idle. It will fire right up and you will be ready to go cruising almost immediately. TUning on a dyno would be best to get the last bit of power out of it.

This will be my second install.

 

How critical is it to have the exact info on your "engine combo"? For example what if you don't know the exact cam grind or valve size, etc.?

Is this a flashable chip or is it set "as is" by Edelbrock?

They will re-flash it for you.
