468 ci

I currently have a freshly rebuilt 454 bored .060 and would like to stuff this into my 1984 Z28. what would I need to upgrade for this swap?:feedback:

everything.... tranny, rear end, DS, headers, SFC's, suspension

[duckman]

ok, tranny is a 4l80, distributor and carb are reworked from the 305, rear axle is a mosier 12 bolt 3.73 w/eaton posi, suspension is an eibach 1" drop, sfc's alredy installed, and a 4 point bar over backseat. what I'm looking for is the other stuff, like brake booster, fuel lines, other small stuff.

[Cashmunson]

well you'll definitely need a good electric fuel pump and bigger fuel lines. what cfm is the carb that you had reworked? you're gonna need something in the 770-850 range to feed a moderate built 468. how are you going to make the 4l80 work with a carb setup?

[duckman]

I've got the stand alone box from P.A.T.C., the carb was reworked to 800 cfm by the Carb Shop. actual flow bench specs are 831 cfm. the cam is rather mild 260* duration with .475 lift at valve. flattop pistons provide 8.5 :1 compession on 118 cc heads. Edelbrock performer 2-0 manifold. will need to find a good set of headers to stuff into car. (I know there hard to find for our cars may just have to build my own) Plan on running true dual 2.5" exhaust. considered removing factory fuel tank and placing fuel cell in back hatch well. you had mentioned suspension work earlier, other than slightly heavier springs for the front what else would need to be done.

[Cashmunson]

well if you plan on getting any traction you'll have to look at aftermarket suspension parts. you'll need LCA relocation brackets, new LCA's, new panhard bar, new torque arm, driveshaft loop for safety.

why is the compression so low? are you planning on running forced induction down the road? i believe there are a few companies out there making headers for the BB swap you're doing into a third gen. that cam is pretty mild, are you just trying to build a very well manored BB for the street? the cam in my 350 has more then 475 lift.

nah just gonna pull it out of the ole 75 c10 pickup. tooo lazy to change cams.
current output is 375 hp and 525 torque at flywheel
