Hey guys. I'm building a new 306. I'm trying to get a estimated quarter mile and a estimated horsepower I'll be putting out. Here is what's goin in the new build. Bored .030 over with notched flat top pistons, e303 cam with 1.7rr's, all new and upgraded valvetrain, original 93 cobra gt-40 heads, trickflow track heat intake, 70 mm tb, a c&l 73 mm maf, and a bbk cai. Exhaust is bbk shorties, off-road h-pipe, and Borla xr-1 mufflers. I have a king cobra clutch, stock t-5, 4.10s and I'll be running either nitto555r or nitto nt05r 275/40r17. Suspension upgrades are bbk front lowering springs and I'll be installing 4cyl rear coil spring, Frpp rear control arms, a bbk strut tower brace bar, and probably a rear sway bar. Any info will help. I realize this isn't the best engine build but it's a temporary build.
I ran the car at the track with nothing but a 70 mm tb, a spectre filter, stock maf, shorty headers, o/r h-pipe, and slp lm1s, 4.10s and stock 225/55r16 rears was a 14.2 @ 99.2. At the time the car had a bent push rod which forced me to shift right at 5k. 60 ft times sucked because of traction problem but I know the car would run around a 13.8.
Later on I will be changing the build for a comp xr270 cam and afr 185 heads as well as longtubes, x-pipe, and keeping the borla xr-1s but for now this will be my daily driver
