i put 80 and 91s in it and it seems to like it alright. but im curious about my heat range on my plugs im running a ngk fr5 should i go with a fr6 or 7 or is the 5 ok it is detonating on pump gas (92 octane) @ 34* total timing I would really like to get by on pump gas

[abigassbowtie]

well i took it out friday and it didnt do what i was hoping but i only got to make one pass before i broke an axle shaft on the launce

i ran a 1.9 60 foot
and ran a 13.21 @101mph

I know it has more to come it is running smoother and better than ever but i need to play with timing and stuff i had adjusted it to 36* when it broke the shaft we will see in a week or two how it does when i get new axles

eric: where do you get your custom axle shafts in 35 spline chromolly?

[abigassbowtie]

i got my axle shafts ordered yesterday i got 35 spline this time and i got them in chromolly. I bought my axles through dutchman and i paid 330 shipped to my door

[ericnova72]

My Nova has Dutchman's in it, found them cheap on Ebay when someone was upgrading to a larger axle. Everything else I've done has had Moser as they are only about 150 miles from me.

A friend has used Superior without problems, but I think they are just stock dimension replacements.

[abigassbowtie]

yeah dutcman is only 250 miles from me in fact if it werent for me wanting to race this coming weekend i would have saved the 30 dollars shipping cause im going up to portland for a psca race on the 11th

[abigassbowtie]

when i oredered my axle shafts they informed me that my bearing journal was an odd ball size at 1.625 they rarely see so they suggested that i change that to 1.531 so my new bearing part number is 514003

bearing dimension is 1.531 id by 3.150 od

[abigassbowtie]

i shaved maybe another 100 lbs off of the truck and let a friend drive it down the track once and he ran a 13.1@103 i really think that it needs bigger headers

but i dont know why the hell i cant get the 106.3 mph again i think this thing should be running 110 mph

[abigassbowtie]

well i think i figured out why my mph is so low I pulled a few valve springs off and checked them and they are 130 lbs @1.900" so time for new valve springs im looking at the k-motion #k-1100 ! think those will be good? man i hope this thing picks up 10 mph

[abigassbowtie]

got the new valve springs

[abigassbowtie]

well the reason i didnt post after running it with the new springs is cause i was pist off cause it threw a rod at the end of the track im looking at some options and would like to hear some opinions I have 2500$ and would like it to not cost over that

turn key ls 5.3 tuned to 325hp

start all over with a 496 I have a 427 t with a bent push rod and I have some ok oval port heads that would need alot of porting and bigger 2.250 valves or buy pro comp aluminum heads and a solid flat tappet cam with 10-1 compression

or build a new short block for the 406

[abigassbowtie]

well i got a 76 chevy truck with a good running stock 509 400 block Im thinking about throwing my whole top end on it and seeing what it does i know its gonna lose alot of compression but its something i could have going by june

any thoughts

[abigassbowtie]

well i parted out that motor started to build a 496 and got sidetracked when I found this nova for sale I drove it home for 1500 straight six and a glide



heres the parts car i bought for 1k



and here they are getting parts swapped

[abigassbowtie]

i got the weld wheels and tires the 8.2 ten bolt 5 lug and a disk brake 5 lug front end another set of v8 motor mounts and a nova oil pan and a bunch of random little parts the yellow car is pretty rusty
