Hey guys,this is a cool new forum!!I"m building a ls1 drag race car but my street car is a 1981 2nd gen Camaro Z-28 original 4 speed car.It now has a .040 over 400 smallblock(408)with Vortec heads.The rotating assembly is all Scat,6 in. H beam rods with SRP dished pistons also Total Seal gapless rings SCR is 9.75.The Vortec heads have beeh ported to 185cc intake and 80 cc on the exhaust,the intake flows 68.7@.100,143@200,206@300,252@400.252@500 Exhaust flow is 60@100,136@200,178@300,197@400,207@500,215@600.I ported these heads and had them flow tested 3 times,with stock valves and with the 1.6 and 2.02(.100 longer then stock) REV stainless necked down stem valves.The intake was opened up in the pushrod area to the point the outside of the port had to be welded.These heads have 7\16 ARP studs and Comp 918 springs.Valvetrain is all Comp,Cam is a custom hyd. roller intake is 230@.050 with .550 lift and exhaust is 236@.050 with .550 lift LDA is 109 and ICL is 107 ATDC.The roller rockers ar 1.6 Magnums with Comp .100 longer then stock pushrods.The timing set is Cloyes adjustable double roller set,covered with a Comp 3 piece timing cover.The balancer is a Fluidampner 8 in.It has March pulleys on the surpentine belt drive from a 92 RS Camaro.The waterpump and fuel pump are Edelbrock,The intake is a port matched Edelbrock RPM Air-Gap Performer with a 750 Mighty Demon carb,air cleaner is K&N chrome 14 in.x4 in.The headers are Hedman 1 3\4 with a 3 in. Dr.Gas X-pipe that goes to 2.5 Borla stainless oval mufflers with a 20 in extension that runs under the rearend,it sounds great!!!!A Griffin aluminum radiator with a 92 RS electric fans keeps it cool.The distibuter is Proform with Moroso 8 mm wires and Autolite plugs.Timing is 34 degress.The flywheel is a 22 lb stock unit with a HD clutch and pressureplate,trans is stock 4 speed,3.42 gears with a limited slip rearend.
Suspention is all Hotchkiss with Moog tierod ends linkage,etc.The steering gear is from a 92 RS(quick ratio)The front subframe has solid aluminum body mounts as well as poly A-arm bushings.The front Hotchkiss springs were cut 1\2 coil to get the wheelwell down even with the top of the 25" tires on the front,back is about 1 lower then the 28'tires.Brakes are HD stock for now!Also I have a set of self fabricated adjustable tractionbars as I have tore up 2 rear U-joints.
The interior is pretty much stock except for the leather seats from a 2000 TA and the gauges from a 1979 Z-28 with a 130 speedo,I also installed a tilt wheel from another Camaro in this car.The exterior is black with the factory stripes(silver) and the 15 x 8 factory aluminum rims,tires are front 245 60"s rear 275 60"s.Future plans are Baer brakes and 17 in painted American Mohawk (looks likeTT2"s except with painted centers (dark silver)and clearcoat finish).Also MSD billet distributer and AL6 box with rev limiter.Also bodywork and paint job and complete new interior with race type seats,belts,etc and a killer sound system.
The car is very docile to drive has a killer idle and is plenty fast,I"ve had it to the track one time and my best time on the 1\8 mile is a 7.59 at 89.9 mph and a 1.9 60 ft time,this was on very slippery BFG street radials(not drag tires)I believe with some et slicks and some tuning it will go into the 6"s!! |
