225 long rod stroker, HELP

My build is as follows: 66 Valiant signet
Bone stock 225 short block. Just reringed and bearings. Stock cyl head with a little blending in the valve pocket, and milled to get 39cc chambers, and 340 valve springs. Old "Racer Brown" st-21 cam 520 lift 286 adv dur. stock pushrods. Offie intake, with a 390 VS Holley 4bbl. Clifford shorty headers. Electric fan and water pump. Electronic dist, with a msd 6 box. The distributor is fixed/locked at 18 degrees since I do run nitrous, so not ideal for NA. Car has a 9 1/2 edge converter (almost 4,000 stall), and 3.91 rear, with 26x7x15 slicks. At 2650 lbs race weight, the car runs 14.4's in the 1/4 mile, and 9.1's in the 1/8 mile without nitrous. The Wallace Racing calculator says the is 174hp in the 1/8, and 175hp for the 1/4. Is that real world enough for you?

PS: On nitrous it runs 7.9's in the 1/8 which says 265hp.

My total cost building the car is under $3000 including buying the car

PPS: My 66 Cuda (sold last year) with a 170 on nitrous, and 3250 lbs ran 12.90's
which is 298 hp. also had a stock short block, except for cam.

Now lets see some of the same type of info, from other posters. Put your actual numbers out there for everyone to see. I know slantracer, personally, and know what his car can do, it runs 10's in the 1/4 without power adders.
