I must expect alot out of a 383. I pulled 350ish at the wheels with a Th350 and HOT cam with LT4 heads and it is still rich.
Either way, I am glad to see the after market putting out parts for the Fbody. But cant wait to see the prices come down, same parts for an Fbody compared to a stang is 50% more, ie the Kmembers, Fs are 450 and Fords are 300 or less...oh welll...

actually, a Hot cam is .525"/.525" and 218/228, with a 112 centerline, so it is very comparable to the Comp Cam 503-8.
A net rating of 420 hp out of a 383 is a lot. Remeber that it wasn't too long ago that 1 hp per cubic inch was a good rule of thumb for a peppy street engine. This isn't a race engine by any means. It was concieved, designed, and built as a reliable street engine. A good friend of mine has a 383 in a 1996 Z28. It puts 360 to the wheels and runs 11.60's.
I am open to suggestions though. If there are enough people who want a 500+ hp 383 LT1, I am sure I can get one built. It would be a cam change, more compression, and some head work away.
As far as tuning goes, I would recommend PCMforless.com or a do it yourself PC based setup like LT1 Edit or Tunercat. Summit doesn't carry those brands, but links are available through this site.
Thanks for all the input.

When you come in, look to your right. There are posters sticking out from the wall. The 2nd one from the front has a picture of my car
10% off sale is June 7th during Super Summit (retail store), so if you don't mind standing in line and fighting traffic, you can save some $$$

That 10% off sale looks like an opportune time to do my cam setup. Nice. I will have to note that somewhere so I don't forget. Their last 10% off sale got me a new set of ET streets.
Now for the power to use them. lol.

I really do wish I could get my advertising department to advertise here. I am still working on it. However, i will counterpoint that there is a strong possibility that if you race, you have seen our banners at your track. That's because we have been supporting tracks all across the country for years. That takes a tremendous amount of money from the budgets. We sponsor the biggest race team in the country, and pay contigency in 5 different race series.
And to pat myself on the back, Summit can influence manufacturers to develope new products for the LT1 and LS1 better than anyone.
I feel we support the LT1 niche pretty well, could we do more, certainly, and I plan to. But don't make a hasty decision. Support this board, as I do, but don't forget who has supported this industry for 35 years.

if that is rwhp, then it is totally acceptable. even though a heads/cam/bolton LT1 will make the same PEAK power, the 383 will make more power under the curve and be a much faster car.
search the board, you will see most peoples 383s only make 400-450 rwhp.
so 420 out of a crate motor would be sweet (with mild cam/heads).
but like i said, if that is 420 flywheel, id be kinda disappointed.

I started that thread several months ago, and have been sending links to it to the product manager at MSD. They have been having weekly meetings discussing this. They have quotes on the machinery (lots) to make new LT1 castings, and they are investigating sources for the cap and rotor. The problem is the variations on the optispark from 1992-97 prevents them from making on part number, which makes it more costly to produce.
It isn't a sure thing, but it looks closer now than ever.
Find that thread and post on it, slomofo, and your opinion will be given straight to MSD.
Thanks.

Well, I for one have had nothing but GREAT service from Summit!
I have only ordered one time from Jegs and it was OK, but Summit ships really fast and its always right. The times I have had a return, it was perfectly handled....the way it should always be.
I am jealous of those who can shop the store in Ohio, I wish Denver had a real performance parts store to "browse". Sometimes it is just nice to be able to "see" and "touch" the items before plunking down our hard earned cash.
Scott, I have to say I am happy to see the LT1/LS1/TPI section in the catalog. It seems to show the same stuff most of the time, maybe a suggestion to change it up a bit if ya can. I know you carry much more for our cars than you list in that section, maybe you could put items that may work for others, but that you may want to target to "the real cars" (just MHO). You might be surprised on the response you would get....
Thanks for the work that you are doing for us, maybe you should show those EXEC's at Summit these type of threads?

It is a non roller single chain (link belt), for shaft drive distributors. I believe that would be 1992-94 Non vented Opti's only.
I am going to see what Lunati can do about offering a roller version for both shaft and pin drive distributors.
Sorry for the confusion.
