I will also say I know this is an old post but I saw some LT1/LT4 cam comments way back that I will disagree with. S10 Converter and a F/Y LT1 cam should have come in these trucks and vans from the factory. Off-idle to 4,000 rpm is the same power, above 4,000 the car cams run off and rather than dying at 4,500 rpm the keep on pulling until 5,500. I have driven and towed heavy trailers with both the LT4 cam with 1.6 rockers with a S10 converter in my Express and a F-car LT1 cam with 1.6 rockers in my brothers Suburban. Both ran and towed much better than they did stock. Not to say there are not better cams but the 395' cam certainly is not it!
I have to disagree with some of the F car cam opinions here. In my race class a stock LT1 is a popular option. Occassionally a machine shop will mistakenly order a B car LT1 cam and install that. When that happens, the cars dyno 23X whp and 33X wtq. With the F body cam and restrictor they fall into the 26X/31X range. The wide LSA and later timing events really reduce cylinder pressure and it shows on the dyno. On my LT1 that cam pulls right to the rev limiter. Lug it down to 3000 and you'll get passed. Regardless of how torquey it is the car is still faster when it's strung out. Though it sucks the way stock and 395 run out of steam so hard up top, they really come on hard in the midrange. The LT1 never really swells, it acts like a cross between SBC and LS. It's never really off, but also never noticeably on either. It just goes.
I'm routinely at or under 2,000 RPM once up to speed with a trailer. Blower helps too.
