i went to the machine shop yesterday to get my bottom end balanced, & before i left he told me that sence i'm going to shoot a 250 shot of nitrous on it, it wouldn't last long. he said the main webbing would come out of it. so i'm looking for a good affordable after market block. what i want is every thing in it's stock location, & the big 400 mains.
the dart lil m block would be great if i could afford it, so would a motown, but i don't have $2,000 to put in a block. i even asked about a 400 2 bolt main with splayed main caps, he said it would still bust out the webbing, just take it longer to do it. if i would have known this, i would have built a 383, just for the fact that the 350 block is stronger.
by the way, this is for a street car.
i'm pushing a little over 500 hp out of it, & with the n2o it would be 700-775 hp.
please tell me where i can get a affordable block. the bore is 4.155"
