Thoughts on Cam Only Record
Thoughts on Cam Only Record Ive been thinking about going for this record lately. (JUST THINKING). My engine now is rebuilt (PRT) ls1 with stock 806 heads home ported on intake side, my cam is 223/227 Smallwood cam. It makes 410rwhp on a dynojet. Car has ran a best of 10.28 @130.6 with 1.35. Best 60ft being 1.34. Car has 2990 race weight.
Anyways I was thinking about trying to find a stock longblock and sticking a big cam in and trying for the record. Car should make similar power as my motor does now or maybe a touch more with big cam. I know I can pick up some et with a 3 speed Trans/with transbrake and looser converter. Still have y-pipe and muffler I can ditch. My buddy has 16v battery I could use and ditch the alternator. I'm switching to a hardtop this winter also. I think I can shed around 100-150lbs total.
Biggest challenge would probably be finding a "fresh" longblock since they haven't been made in over a decade. Can it be freshend up with new rings/bearings? Any lifters? Any cam just no fly cutting?
Im guessing that the 9.98 record still stands?
Again this is just a thought right now and not my actual plans for the car at this point. Im open to thoughts and ideas anyone has just please no **** talking.

Not like anybody is the authority on this, but would most people consider ported heads to still apply to the "cam only" record. My opinion would be no, as in theory you could just as much flow out of hand ported heads as you could a company's CNC ported castings if you know what you are doing.

Going to need a trex or bigger cam, 2700 lb raceweight, be willing to put 35-38 degrees of timing to it, spin it to 7500, a good lightweight super stock like driveline with a th350/400,and -2500 da conditions like found at atco in November when that was run.
Yep we have some really good air this time of year. I ran 132mph today but the track prep wasn't the best only ran 10.36
Not yet I'm still deciding if I want to go for it but Id definitely consult Martin and Shawn @ PRT about a cam. Those guys have forgot more than I know about the LS game.
I always wanted to try one for a cam only with a single plane intake like a super victor, something like a 254/260 with about 590 lift, Lsa at around 104-102, and put some advance in it. Likely gonna have to notch pistons.... but I bet it would work well. 8 or even a 7 inch 5500-5800 converter and spin it to 7500, 4.30 rear 28 inch tire. Race weight has to be 2700 or less.

That sounds like it would fly in a lightweight and good working chassis.
I think ssperformance set the 9.98 record with no fly cut Pistons. I really think I can go that fast with the Fast 102 on my car now. If I can drop around 100-150lbs that should be a tenth. Transbrake is worth? Bigger cam revving higher is worth a bit.

I doubt I'll get mine below a 3000 lb race weight, at this point I think mine will be around 3200lb min. I'm not sure how big a cam he would spec, I want the most I can get in there and I plan on running some roller rockers. I want this setup to last a while so I want a little milder lobe design vs the xer lobes. If I can get mine in the 10's stock internal this winter I think I could run mid to low 10's with a cam.
Most people want a good bit for a stock ls1 and I worry if I had to buy another it would end up having problems. At least with an 01 or 02 model you can sell the ls6 intake and get some money back.
I think it's doable to run faster than 9.98 cam only in a 4th gen. How hard will it be is what I'm curious to find out.

I'm telling you, 2700 lb raceweight. A lightweight internal super stock style th400, 5200-5600 8 inch converter and a 4.30 gear with some of the lightweight Hoosier radial slicks... that stuff on a day with a -2500 da, oxygenated fuel and a tune set for kill. You want to break the record it can be done but you have to go for it, don't try to 1/2 *** it with some mild cam lobe or any of that.
The fast intake that's really tall the lsx rt or whatever that one is if you're not going to single plane it would be best. Plan on cutting the car up anyway as it's gonna have to be to get it light enough.

Those th400's like that will just cost too much for me, if I was gonna go to that extent I would run the crate engine class and get one of the g force 4 speed manuals since they finally allow a manual.
I'm gonna try out this clutch tamer slip device and see if I can't get some et with it. I'm more curious than anything to see what kind of gains I could get out of it if any. I would pick up at least a tenth with ms109 in the car, I feel like I'm cheating running that expensive stuff.
