I might have mentioned this in another of my posts.

That is very close to the Elgin E1135. Elgin can is 210/215, .462/.470 on a 110 lsa.

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 mean I do not recomeend the 395' cam for a stock Vortec. You can get almost the same power bump by adding 1.6 self align full roller rockers.

when googling e1135 cam it doesn't shows those specs(just FYI)

correct specs are for the e1136 camshaft

Sorry it is E1136...The E1135 is much bigger. 230/230. Mixing the last digit up with the 395' cam.

100$ cheaper with the same specs as that "dr. bumpstick" cam

Only real difference is the LSA.

 

[sharpe.trey]

what the LSA effect? Excuse my ignorance...

Overlap and a slight change in powerband. Generally tighter LSA makes for a rougher idle, less vacuum and a peakier powerband. Wider LSA makes more vacuum, broadens the powerband and increases vacuum. 2° on a cam that small will hardly be noticeable especially with a restrictive exhaust.
