I iniciate the modifications in my car in 2008, for street aplication. Initialy I use a 4inch pistons, ISKY cam (525B) with 278x278 intake/exaust duration, one 4barrel Holley 750cfm and a spray with 70hp of NOS. The car in street is realy very funy!
In 2010 I change the configuration, with more compression (13:1) for methanol, a CRANE cam (310x320 intske/exaust), a dome pistons, and the same 4barrel (but with some modifications).
On this event, with ethanol, the car makes 2.0s 60ft and 8.6 1/8, but the best car times is 1.9s 60ft and 7.7s 1/8 with DRAG radial and 2.0s 60ft and 8.3s 1/8 with street tires.
This configuration is very popular in Brazil, for street or strip use, meanwhile with 3 40 or 44mm webber.
The best time on this class in Brazil (with street tires and 3 webber) is: 1.8s 60ft, 7,4s 1/8 and 11,6s 1/4 (pilot: Danilo Aizona by Segantini) on Curitiba/PR strip.

With DRAG radial is 1.6s 60ft, 6,9s and 10,7s (pilot: Celso Camargo by Benato) on Velopark strip.

However I need some help to the development of my new engine, mainly before read some parts of Leo Santucci´s book and see the movie about Perry and Headrick "Pocket Rocket" car, then win some race on NHRA on late´s 70´s.
What the best block to use on darg race with Drag radial, 250 or 292? And compression rate? 3 7/8 or 4 inch pistons? And the camshaft? With or without lump ports (in Brazil NOBODY use lump ports on the head).
I appreciate any help and get post more pics and movies about TO - Traseira Original (Rear Standart) and STT - Street Tração Traseira (RWD Street) class.
