FE Engine Dyno Results / Re: Lykins Motorsports 434ci Clevor, 777 hp/630 tq

So the FE dyno results aren't free advertising?  How does that work? 

Perry, you're the only one who will praise me in one post and cuss me in the next.  You need more fiber in your diet, brother.

Jay, it's a 260cc port that flows 400 cfm.  Cam specs were 260's/270's at .050" with .825" lift at the valve.  It also has a GZ Motorsports vacuum pump on it, which I forgot to add up above. 

Car is a '69 Mustang.  Runs 9.70 at 141 mph with a 1.58 1st gear Powerglide.  He had aspirations of spraying it so he wanted a softer dig.  Would love to see what it would do with a real transmission LOL  It doesn't come on hard until half way down the track.

Minimal specs will be given - as this is a blatant form of FREE ADVERTISING on this FE forum.

No wonder there are less and less users on this once busy forum.

Very sad to see.
All the upside down whackiness in the world and this is what bothers you?  Being a pill is no way to go through life.  You (everyone) needs to find what makes you happy and focus on that.

Rory, no smoke and now that you mentioned it no little pebbles or rocks stuck to the tires at all. I remember my Firestones on my super gas car would pick them up like crazy. The noise driving back to the pits with all the little pebbles hitting the aluminum wheel tubes was loud!
I’m leaning toward a lean miss but it didn’t get noticeable until the second day. The air was only slightly better that day and hard to figure how a small change caused the problem. The rocker and new valve springs were all fine and all the plug wires were making good contact.
I think I will jet up 3 or 4 sizes, raise the rev limiter farther away from the shift light rpm and order some new tires. Oh, and some new plugs also.
Looking at the plugs that came out #2, #6 and #8 look like they are running a bit too lean.
What do you guys think?

Mike, when you did your burnout, did the slicks smoke right away? I have always found that fresh slicks wil smoke right away, but old hard tires, take much longer to get the smoke rolling off them. Hardly scientific, but could indicate how subtle the rubber compound is after sitting several years. Also, soft tires will usually have lots of rocks sticking to them, but older tires don`t cause the rocks to stick as well.

My Mickey Thompson ET/Streets never did smoke. I made sure when I got them that they had a recent date, and it was within a month or two from purchase as I recall. Even 2nd gear burnouts in the box produced no smoke. I always thought that was odd because everyone else at the track would always smoke pretty good on the burnouts. They have NO problem picking up rocks though. Even on the street, a rolling spin in first and a slight spin when hitting 2nd is enough to heat them up enough to grab every stone in my driveway and throw it up under the wheelwell. ::) I've had some traction issues from the get-go, and despite making changes to the Cal Tracs, shocks and tire pressure, it seemed hit or miss. I always wondered if the tires were at least part of the issue. I guess only a different set would tell me.

If MSD is involved in the ignition, after checking power and grounds, first thing I'd try is a different pickup, then go from there. I've had more than a fair share of issues with those crappy pickups.

I'd rather not see every run of the mill non-FE engine, but an interesting build like this one is OK.  No Chevys, though  ;D  Would love to see head flow numbers and cam specs on this one...

So there is some more news about this bellhousing.
It comes with the block plate and hardware.
It also should have better ground clearance than a SFI Quicktime.
It does not have the lip for the bolts on the bottom.
The Lakewood is 1 3/16" closer to the road than a stock bell and inspection cover.
And it's like wedge digging in when they hit.
I am talking myself out of that Lakewood more and more. ::)

FE Technical Forum / Re: Cometic MLS head gasket misbuilt?
« Last post by Jim Comet on April 23, 2024, 06:36:16 PM »
I talked to Cometic and this is their standard design for the FE gaskets. I believe the exhaust chamber has been laid back on my ProPort heads which may be the cause of the overhang. My old round chamber design 4.165 Cometics did not interfere so I ordered a new set of round 4.170 MLS gaskets. I'll know in a week. Jim
