10 second N/A LT1 combo's???
10 second N/A LT1 combo's??? Hello,
I am planing to install A LT1 in my 69 camaro. Currently have a 383/glide carbureted combo looking to go injection. I am wanting a motor I can drive a bit not across country just around Town on weekends. I am looking for a 10 second N/A combo then I plan to install my Direct Port. I am Fairly unfamilliar with injection and the LT1 so any info you have on the engines and possibly the swap into a 69 would be greatly appreciated. Also any info on how much HP the factory Fuel injection will handle. I have a set of afr 210's I plan to install, In my current 383 I have solid roller cam motion shaft thats 620/640 lift 252/260 @ .050. Will this cam fit in the LT1 block and would this be a decent choice for the motor. Thanks In advance for any and all of your Help.

Are your AFR heads for the old style sbc, or the LT1? If they are for an old style they will not work as the LT1 has reverse cooling passages. They could be modified to work, but the time and expense may not be justifiable.
The stock PCM (computer) is limited to 7000rpm so that may or may not be a factor in your cam grind.
I would do some searches on this site and others, to see what some of the faster guys are running. Here is a link to another good site: http://web.camaross.com/forums/
Good luck with your quest of hitting 10's....

I don't think 10s N/A is a realistic goal, but mid 11s could be achieved with great effort and expense. With a little research, I think you'll come to the same conclusion. Very few people have broken into the 10s with an LT1 all-motor.
I asked how much money it would take to get a forth gen LT1 M6 into the 10s N/A on the big LT1 board, www.camaroz28.com. From this thread http://web.camaross.com/forums/showthread.php?t=311003 here is what one guy said:
I don't have any interest in sinking $24,000 into a car that would suck to drive on the street. Here is some advice given to me in the same thread by a different person:
I would take a look at LS1s on eBay if I were you. http://cgi.ebay.com/ebaymotors/ws/eB...933815044&rd=1

SO to answer your question $20 g's+ to go reliable 10's on motor, from the flywheel back gonna cost ya $4000.
My sugestion unless you want to turn your car into a track car. Get a good heads cam setup..put a rear end and some suspension under it...and be happy with high 11s on motor..maybe try to spray it to the 10s..but even that won't be easy.
A buddy of mine has a 1994 Z with a Nu-tek built 396 solid roller around .610 lift. It has GTP ported stock casting heads, around 12.5 to 1 compression and still has a 6spd with a moser 12 bolt with 4.10's. It went 10.80's on motor.
10s NA on a stroker LT1/solid roller/AFRs should be expected. I had a 396ci LT1, AFR 210s, cam motions solid roller (247/250), and a near full weight street car.....trapped 126mph in the 1/4....good enough for 10s if I had a 12 bolt in the car at the time.

The computer for an LT1 will only handle 7200rpm - however, I believe Accel and FAST may sell "piggy-back" kits that will allow it to go higher. Not going to vouch for how cheap those would be. I don't believe your cam will work, but I know the rest of the valvetrain will (rockers, springs, pushrods, lifters). Your heads can be converted to reverse cooling, but I'm not entirely familiar with how that is done.
Really, if you want 10's N/A, you're probably better off sticking with a GEN 1 block and putting injection on it - especially if you already have all the hardware. GEN 1 blocks (aftermarket ones, anyway) are better made, stronger, etc. When you're all done converting your GEN 1 parts over to be compatible with an LT1, you'll have spent what it costs to get fuel injection on a GEN 1 motor anyway, IMO.

Theres a few holley commander efi setups that are pretty nice they cost around 2000 but are suppose to pretty easy to install and tune you may wann alook at those options....also tens arent really that hard to get out of a NA Lt1 especially in a lighter car but it would definetly have to be stroked

Heres a list I made of some of the fastest LT1's in the World. The N/A list is about halfway down.
http://web.camaross.com/forums/showt...=305819&page=1
As you can see there are quite a few N/A LT1's in the 10's, and the list isnt even anywhere complete.

All it takes are the right heads and a good cam. I will hit 10s on the next trip to the track 
BTW I'm talking about a bone stock bottom end with over 110,000 miles on it

Its really not that hard get 10s. We have a 97 Z with a 383. Cast crank, stock rods, ross pistons, cc306 cam, locally ported stock heads, 52mm TB, hooker supercomps, true duals, b&m 3000 holeshot converter, TH350, draglites/et streets, full BMR suspension, stock rear and 3.23 gears. This car goes 7.1s in the 1/8 all day long, with a best of 7.04@97mph. All of this is also with a mail order tune that wasnt really for this car and the only weight reduction is sparetire, jack, and front swaybar. With a dyno tune and more weight off the car it'll run consitant 6s. The key to this car is the 1.4 60s, which will probably take its toll on the stock rear before to much longer. But then it will get some gear and that shouldnt hurt either. Anyways my point is that I beleive that 7.0 in the 1/8 is pretty close to 10s in the 1/4. And this is a very cheap setup. You shouldn't have that much trouble getting 10s. Good Luck.

1995 Z28 1LE
355 LT1, Stage II LT1 heads, hyd roller cam, TH400, Mufflex 4", 11.75:1 CR, pass made on a 150 shot (I have 250 jets but the stock fuel system would make that a suicide run)
10.40@130.7
backed that up with a 10.44@131 mph....
Video of the pass is on www.bmrfabrication.com in the feature cars section under jason brisson..... If you could update the list i'd appreciate it.....

By the way, my opinion about dropping an LT1 into a Gen I car and getting it into the 10s still stands firm (especially considering that you said you wanted it to be a cross country driver!). Take a look at that list and you'll see what I mean.
Anyways, all I said was that it wasn't a realistic goal; instead try high to mid 11s. Do a little research and I think you will come to the same conclusion.
I'm considering a 383 with stock casting heads for the car in my sig. My hope would be mid to low 12s, but I'm driving an M6.

Realistic goals? Those are crappy goals. No offense, but there are alot of guys on this board that have bad combinations or can't drive and they are giving these cars a bad name. You only want to run mid 12s? It only takes 350rwhp and a decent 60' and you should easily pull a 12.5@~110. Alot of people have this and more especially LS1 guys. But they have bad 60's so instead of buying some good tires they go with a bigger cam or something like that to make more power. When really power wasnt' the problem at all. So now they have more power, hook less and run a similar time. Low 11s should be expected from a car with 400+rwhp. Which is possible from a 383. All of this ofcourse is assuming your track isn't in the mountains, but entirely true if you live in middle to eastern NC.

And if you read closely he said he didnt want it for crosscountry driving, just around the town.
