1990 Iroc Z Camaro (427)

My 1990 Iroc Z Camaro getting fired up after putting in a 427 dart small block chevy and a freshly rebuilt turbo 400 tranny with a trans brake. The motor was dynoed and is making 700+ horsepower and 600+ foot pounds of torque. Im running the motor on E85. Using a quick fuel 950 cfm double pumper e85 carb. Full interior (power seats, power windows, full stereo with subwoofer, stock 15 gallon fuel tank) fully street legal and will be running low 10's in the quarter mile at about 135 mph.

how'd you do ur exhaust? i have a 434 motown in mines and i had to try all kinds of tricky shit to get true duels with n Xpipe

[MrDart427]

mine is just true duels. it doesnt have an Xpipe. i came straight back about 10 inches off the headers on both sides. cut a descent sized slash cut so the pipes were slash cut to the outside. slash cut another pipe about 10-12 inches on both ends so i could get to the outside of those miniature frame rails. after getting the angled cuts right on the pipe i slash cut a straight pipe (times 2) so itd match the pipe with the the slash cut in it already.

i then went straight back, mounted the exhaust off the crossmember of my torque arm on both sides. turnout tips allowed me to exit before the rear tires. to tuck the exhaust up under the car better, i used a plasma cutter to cut a rectangular shaped notch out of both of those frame supports. i had to oblong the rectangle so the exhaust could come through. after that i plasma cut some flat iron to fit the holes to cap off the hollow channels of the frame to reinforce it and welded the plating in

im not sure how long you can wait. but im still waiting for the snow to melt down at my shop to get my car down the sloppy gravel road. still gotta put the carb on, put all my rocker arms on, and set valve lash. i could put the car up on the hoist and take a video of the car from the bottom so you could see. i know my explanatiion would be very difficult to understand without seeing it

Super clean man. I just installed a Motown 434 sbc in mines with a 400 trans. How did you mount the torque arm on the trans? I'm going through that issue RIGHT NOW.

[MrDart427]

my torque arm doesnt connect to the trans. i have welded in sub frame connectors. then have a round tube cross memeber located behind the tailshaft about a foot with a drive shaft loop welded on the cross member. my torque arm bolts onto that cross member.

[twizitedclown91]

will the 427 drop right in and bolt right up or does it have to be around of cutting and welding

@ddirty2102000

you can fab ur own i did jus get a stock camaro 5 speed crossmember n get a 400 tranny mount n weld her on but be sure to reinforce around the crossmember

revs quick

[junior17817]

@ddirty2102000 summit makes a crossmember for a th350/th400 swap that moves the torque arm to it instead of on the tail shaft
