Very impressive numbers. Almost too good. Looks like your combo is perfectly balanced. It goes to show a balanced assembly is better than just big parts. There are tons of guys on the thirdgen site that on paper should be making more power than your setup and they don't even break 400hp or tq and they run stealth rams...
Good going!
Good going!
I would first put 6 quarts in the pan. Then calibrate the dipstick. After that you could put half quart in the filter and start and let run a couple minutes. Then check the dipstick and add to the full line. Total capacity will depend on the filter you use too. The most important thing to do is calibrate that dipstick with 6 quarts in the pan.

Wish i had a super ram intake. Cant even find a used one for my LT1 camaro. J. Lingenfelter sold off the design to Accel before he got a CARB legal Super Ram for the camaro/firebird LT1's into production. I think its a bolt on improvement for torque. It looked like BBK was making a copy cat Super Ram and sold them for the GEN I sbc engines but nothing for the GEN II motors and now BBK no longer makes them. Dont know what Edelbrock was thinking making a copy of the stock intake.
Oh well congrats on a nice build cypher.

I have heard the LT1 superrams are very rare. Are you unhappy with your LT1?

Well I dont race enough to say im unhappy with the LT1 intake. But it dont take much science to realize the LT1 doesnt have a long enough runner to use it for any tuned length within the LT1 7,000rpm limit for its opti. Im used to old school sbc where there are dozens of fairly cheap intakes to match the engines power range and they just bolt on w/o expensive and complicated mods. Im thinking the happist LT1 owners have converted carburetor single plane intakes with an intake elbow. But u lose the smog certificate with the visual inspection let alone the missing EGR function. Hey i'll also i dare say dual plane conversion for a street driven car. But i see any conversion as $1,000 minimum cost and $/hp it somewhat a loser for a budget build.
Only options left are the TPIS mini ram and the Edelbrock intakes which arent much different than the OEM intakes.
Right now i have a very short cam in my LT1 - the 350 RAM cam #14097395 which is more of an experiment for a LT1 cam swap. I have too much wheel spin now but the LT1 intake short runners with large area/diameter never see power peak before the cam stops breathing. My dyno curve is a rounded downhill slope from 3,000 rpm. I expect a long runner intake would pick up the power near 5000-5500rpm. So yea something like a dual plane or the Super Ram would be a better match. Anyways its a work in progress.

Have you ever considered the stealth ram? I have heard it pulls well up top while maintaining good torque numbers.

To tall, wont fit under hood. Has to be modified to bolt onto LT1 heads. Stealth Ram is pretty bad azz though and would like to be able to run one.
Ya know with all the plastic/composite intakes now i hope to see something better for the LT1. I see plastic intakes for the LS motors that are assembled with swappable trumpets/internal runners. But the reverse cooled LT1 is a step child chevy and even CARB legal headers in large diameters are gone/dropped from production. Not any money to be made in producing an LT1 intake.
Anyways for the 4th gen camaro w/LT1, Lingenfelter had to cut down the SuperRam height to fit under the cowl and they never saw a CARB number unlike the corvette Super Ram for the LT1. The base of course should be the same for vette and camaro as both need the LT1 head bolt pattern also i expect they dont have a t-stat housing but havent verified that myself. Ive just been keeping a watch for a 4th gen SuperRam but not really looking very hard.

Greeat numbers!
I cant tell you how many threads ive read where someone tries to do a l98 383 and ends up making less power than a hotcam/headered stock bot end 350 lt1.
Yours is a total success!

Oustanding #s for what you have
Funny how some combinations that are "wrong" on paper actually run pretty strong. Nice job

Canton Road Race Oil Pan
I run the Canton Road Race pan on my 91 and 96. It is called a 7 quart pan. However, of you do get one, you will want to put 6 quarts in the pan and calibrate your dipstick. Then start up the car and finish filling as necessary. I was overfilling at first and kept having to empty my catch can after every event. Finally called Canton and told me the pan just held 6 quarts and they figured another quart in the filter and block.
I am NOT an expert, but assuming one adds 7 quarts PLUS the volume of the oil filter (whatever size one uses) and is NOT running an oil cooler, I believe there will be enough oil circulating while the engine is running that the pan will not be overfull. However, I haven't run this engine yet (still waiting for final parts, etc.).
My purpose in running the larger pan (and this is the ONLY larger pan I could find that would fit the 1991 C4) was to help cool the engine and avoid oil starvation during auto-X runs. I am not sure yet if I'll add an oil cooler (damn Los Angeles traffic and summer heat!). If so, of course more oil would be needed to keep those hoses and cooler full without starving the engine.
I hope this information helps!
Cheers, M

LT1 intakes - try an LT4 intake?
It even passed California smog because the LT4 intake is oem, well, until we put headers on it....
I hope that helps!
Cheers,
