On my 87 258, I installed a holley 470 TA 4 barrel, offy intake, rollor rockers, ported head, header, DUI distributer, MSD and the cam I used to tie it all together was comp cams high energy 4X4 cam, part#X4250H. The 258 screams, runs like a small V-8. It makes awesome power in the low to mid range. It's all good, cause the 258 is a low reving engine anyway, it makes peak torque at around 1,800 rpm's, witch is great for off road, it's like a diesel. It's a screamer in the 8th mile. With 4:10 gears it runs out of breath in the quarter, but it rips off the line.
