im confused on what kind of radials to get street or drag and what is a good one to get im looking at a size of 255/60/15 for my t/a with stock rims. what i have is a t5 powered by a 383 what the hp is i dont know yet with 3.70's soon to go into the rear along with a posi unit. what does any1 think of the mickeys summit# mtt3756r? this will only see the track on a rare occasion but when it does i want it to do its best. i dont drive it much anymore either so its not a dd. id appreciate it if someone could point me in the right direction thanks.

If your 383 is built decently stong, your t5 isn't going to last long behind it once you add sticky tires to the mix.

If you are not ready to buy a new tranny use decent street tires and go for top speed and forget about 60' times. A stock T5 just wont handle the stress.

im just after an overall good 1/4 et time. so what do you guys suggest the i use just regular tires??? im just tryin to get my car in the low 12's if i can do that on the tires i have now 215/60/15's i thought that i would need a taller tire these are 25" i figured these wont handle 3.70's.

i highly doubt a low 12 outta the combo without traction. and with traction, you'll frag your t5. it looks like it's time for you to spend some money there bucko

brutalform

Yep, killed two both behind a 305! One, N/A, the other with a 100 shot.

so should i look at a t56 6 speed where should i look to get one? or what should i start to look for that can handle my combo and how hard can i launch my car without a problem? let me run down the specs of my 383 maybe this will help.
2.02/1.60 64cc/200cc aluminum heads
.480/.480 230/230 110 cam
11:1 hyper pistons
750 permormer carb
performer rpm intake
edelbrock tes headers 3" catback exhaust hallowed cat
hooker comp muffler

man, those heads and cubic inches are BEGGING for more camshaft.

anyhow, i'd buy a Tremec TKO 600 and be done with it. put a centerforce stage III clutch in it and run with it. you can clutch dump at 6K and Tremec will cover anything that fails in it up to 600ft lbs. then you'll be looking at a 12 bolt or 9" to put under the car

I agree with mw66nova, it needs more cam. Look for upgrading the rear at the same time as the trans since both will not handle sticky tires and a high rpm clutch dump.

you guys dont think my 9 bolt will hold up either????? i thought they were built pretty strong. of course not as good as a 9" or 12 bolt bolt but good enough for now. what do you suggest on a cam??? i havent dyno'd as of yet every1 tells me to wait till i dyno before i think of making any changes. in another thread i was lookin at 2 other cams .525/.525 253/253 .501/.501 244/244??? these or any other suggestions? i dont really want to rip my motor all apart since i just got it together not that long ago. i was also thinkng maybe of doing a 100 shot but am not sure since i only have stock rods and arp bolts.

The 9 bolt isent much stronger than the 10 bolt. Dead hooking with 6k clutch dumps is hard on any rearend with a strong motor infront of it.

i figure i'll be launching around 4-5k i dont think i'll dumping at 6k that might be a little bit much tryin to keep it from going over 5500 just bein cautious with stock rods.

mw66nova

iTrader: (13)

even at 4-5K, you're gonna kill that little 7.75" ring/pinion gearset. they ARE better than a 7.5" 10 bolt, but not much. especially if it's filled with mostly stock stuff. i'll let you know how mine handles a decently hard hitting auto tomorrow but i don't think it'd hold up to the potential you have.

i'd like to see you run a camshaft with 240*-250* duration with a split pattern to help the "weaker" exhaust side. you have the heads and cubes for it, so give it some big cam too. a 110lsa would be good too.

so it should have a little less lift on the intake side? also i plan to upgrade to 1 3/4 long tube from hawks after i get everything major settled in. heres a couple more cams tf .495/.510 246/254 lunati voodoo .525/.546 241/249 also how will this effect my springs on my heads will they need to be changed to handle the lift difference. i have no idea what they are set up for as far as maximun lift. i'll try and find out from the people that i bought them from. i personally dont know how to mess with assembling heads and if that is what it is gonna take it might be a bit more than im ready to deal with. i already hate the idea of ripping aprt a new engine but if it will make a considerable difference then i will. my only problem with dynoing what i have now is i already have the rad out right now so if im gonna do this now will be the time.

do you think i might be able to pull a high 11 with the right cam and trans? oh and by the way i have motive ring and pinion gears for my rear purchased from fastiroc off ebay.

at the site i found where i was thinking of finding a tho 600 has two options for fith gear a .64 or .82 which would be better for me with 3:70's? the cost with shipping is around 2400 depending on where i want the shifter centered. where do i actually need it centered at 19.5" or 16.75 and if i should get a stock shifter or a pro 5.0 shifter?

D@#N everytime i turn around i think of another problem with a cam swap and i just thought of clearancing issues since i do have a 3.75 stroke and 5.7 rods i have no idea how much more of a cam i can add without a problem and have my cam hit my rods. i'll have to ask my machine shop if they could even tell me they did it a year ago. i hate to take it apart and have to put it all back together the way it came apart.

you won't need a small base circle cam until you get into "big" lift.

white85transam

iTrader: (2)

small base circle cam isnt that one designed specifically for one motor? if so are saying that the voodoo cam i picked will fit?

izcain

I know from experience. I ran a 383 stroker with a nitrous cam it has only .487 intake and .501 exaust and I ran into clearance issues. If I didn't clearance the rods it would have made contact. You need to be sure to check this before starting the motor. Not everyones motor is the same. It depends on what kind of rods you have and wether you have stock bolts,ARP bolts or capscrews.
