Did any one see the article in this month's Hot Rod Mag about the bolt on 400rwhp LS1?

...they used a very unusual cam, and hand ported heads, right?

RoyO

I read the article real quick and the heads they showed pictures of were hand ported. I guess Mondello racing came up with the cam specs.The heads didnt look like the took to much out of them.

I re-read it lastnight and I think HotRod should come here to see how we all did it <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

What were the specs on the cam they used?

Yeah, i just read it and yes, if they cam on this board we could show them how to make 440rwhp on H/C instead of just 400! <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" />

I reread the article and the cam was a joint between Comp Cams and Joe Mondello of Mondello Techincal School. The specs in the article were .599/.566 lift and 267/275 deg duration measured at .006 lift on a 111lsa. The article give valve opening and closing events also.

..there is a whole lot of development going on with these engines and the press gives us virtually ZERO coverage....


..No wonder magazine sales are spiraling downwards ....they are still doing articles on hopping up your 1969 Z28 ...like WHO CARES?

Those are actually pretty strong gains given the cam. The gains from the heads alone would confirm this. Its specs would come out to roughly 214?/222. I say 214? because it is not a standard comp lobe and is extremely aggressive for the ramps with that small of a adv dur. and high lift, but the exhaust lobe is definitely their XE 222 lobe. I would say it is similar to the TR "Old Man Cam" minus the added lope of the 111 LSA in that it has an extremely aggressive intake and more exhaust duration. But 400rwhp from a tiny cam is not bad at all.

That's the thing... HRM did an article way back when about an MMS car that was making something like 410 to the wheels... then it ran mid 11's on the motor and mid 10's on the spray (NOS 5177 kit, I think). Other than that, I really haven't seen too much on Gen III performance in HRM. Car Craft is a bit better, and GMHTP is a bit better still, but we here in the GM camp are still wanting for the GM version of "MM&FF", where there are lots of feature cars and plenty of technical tests/information.

I just read the article yesterday, Is it possible that the intake lift is a misprint? It seems high, considering the duration on the intake is less than the exhaust. I think it should read .559?

Cam was from comp cams. They did not list what headers or exhaust system that was in the car. I assumed because he has long tubes in cali, and didn't want to get into any trouble. Heads were hand ported.

I just e-mailed this page to HOTROD mag, hopefully they'll read it <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

yeah I don't think HRM quite has the right picture of the LS1. They should have done a story on the 400+ HP cam only cars. That would be more impressive than there 400HP head and cam car. I would also show what this engine is capable with just a cam change (well, and exhaust and the other boltons)

Whoever wrote that article should be labeled "LS1 Clueless". He wrote it all hyped up like this shop was going to be one of the first to make 400 rwhp with a 346ci LS1. HELLO! there are only like 500 of those on this site. One of the first? First what, 10,000 LS1s to make 400 rwhp?

My Formula was the very first on the net to make 400 rwhp with 346ci NA, and that was back in 1999. MTI Stage 2 heads, T1 cam, and LS1 intake and MACs. Back then it was all we had, and the T1 was the very first 112 LSA cam installed in an LS1. It was considered "BIG" back then <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

I don't mind the LS1 coverage, but please just get some writers that know their subject a little better.

They still develop new parts (suspension, brakes, tranny conversions, interior parts, etc...) for these 69 Camaros. Just because the car is old doesn't mean the aftermarket isn't growing.

I know the guy that owns that car, in fact, he let me drive it. I am not sure on every mod he has, but I know he has Hooker longtubes w/o cats into a flowmaster exhaust, and heads/cam. I think he spent over $6,000 for the heads/cam and only got 400rwhp out of it, and he had a service engine soon light on. That was my first heads/cam car that I had driven and I was not very impressed with it.

that guy is my friend and the car did move, but he has the stock rear end in and I didn't want to push it. I expected more and would never pay the price he paid. He does have a cool t.v. in there. He also has a polished holley intake.

robertbartsch

Did they also fail to describe the exhuast system on this car since it is not California emmissions compliant? WOW ...What has this world come to?

...Next the states will be buying up old muscle cars and melting them down so they can say they are improving air quality....what about the air quality in Baghdad - or does the fed not count?

There are laws that propse that "junker" cars be taken off the streets. But they consider a 69 big block Camaro with a rust hole to be a "junker" some places. Thats why there are a lot of people fighting these laws.

robertbartsch

I owned a 454cu big block 70 vette - matching numbers...i sold it recently....no regrets..

...I got $20K for the car and would have sold it to the government for melt-down if they paid me the same dough....

...I'm not sure why the tax-payer money should go into these worthless undertakings but it did not matter to me about the fate of the car....only that I got my maximum investment back...

...any car of this vintage would be driven rarely and therefore, could not possibly have had an adverse impact on air quality....just another dopey way for the government to spend my tax dollars....
