470 broken in.....

and I installed the 2nd valve spring yesterday. But....from the get go, it sounds like a sewing machine. The cam is a Comp XE285HL. Just wondering if anyone has some insight on this? Read a few things that state due to the ramp rate, that's the noise it makes.

Other than that, it's bitchin'!

I have the 275 version of that cam and was wondering what it sounded like and found them on YouTube and both sound pretty docile for what they are.
HotRod did a build very similar to mine and did the 275 and the numers it put down were very impressive 550hp/570tq .
I bet you are doing even better with your setup.
Glad to hear your about done...post a vid! I'd really like to hear it!

Got some loose ends to tie up, then I can take it down the street.

I have the XE295HL in my 500" big block 440 in my Charger and it sounds like the rockers are all loose. Runs like a sum beech though!!! Good power and the idle isn't that crazy at all.

My idle is at 850-900, but I need to tune the Holley Terminator, but it does sound great!

Yea I keep mine between 800-850 but its a 4 speed car so it seems to like it there.

4 speed here also.

I ran the same camshaft 4-5 years ago, i'll post a sound-clip later. Yes, it does sound like a sewing machine (last hyd cam I ran until I went mech), quite a lot of valvetrain noise due to the faster ramp rate.

Drove around the block twice today and she runs good. I had to fight the little devil on my shoulder as I REALLY wanted to lay into it, but I drove like a civilized human being.

Need to address the front alignment a bit more, and add some heat protection to a few plug wires.

another Mopar hits the streets.

The CVF Beast serpentine kit is modified from its original belt routing along with putting the ac compressor down low on the passenger side. I was able to reuse 1 belt and had to order a shorter belt for the crank to power steering pump and that will be here tomorrow. Also scored an ECP 2 row, 1 inch tubes, 26” radiator on eBay for 140 smackers. I will probably have to switch to electric fans due to the lack of space in my 69’ Dart GT, we will see.

Lucky bastard, were they new rads?? I just talked to frank at ECP yesterday

 

[Mike67]

That looks much better! I never cared for the compressors sitting on top, very detracting....

 

[5.7 hemi]

It is a new radiator, has a bent flange, no biggie to fix it and comes with their warranty. Couldn’t pass on it!

Yeah, the ac compressor on top looks like an after thought. The bracket I had to make was simple, but getting 1/2 aluminum to melt was hard, had to put 140 amps to it.

The Beast from CVF Racing is installed, modified and waiting on the shorter 8 rib belt, the 6 was dirt cheap and good for mock up.

If I can get a different power steering pulley, I can make this a true 1 belt serpentine set up.

Got the radiator yesterday from ECP and they screwed the pooch on this sooooo bad! I received a 3 row radiator, not the 2 row that was listed in the auction.
Sent an email to them and they said “we don’t make 3 row radiators so send it back and sorry about this”!
Kinda pissed, now I have to take it down to the post office to ship it back. I did get a prepaid return label, but I was hoping to have it back up and running this weekend.

We need to hear it!!!

I don’t have a YouTube account, so unless someone is willing to post it for me, I can’t do it.

Send it over, I’ll post it for you. You still have my number?

 

[5.7 hemi]

Let me get it running again and I’ll send it to ya.
