Good day Guys,

I need to know what is the duration and lift on the engle 130 cam also is it true that you can use the 1.25 : 1 ratio rocker arms with this cam, also how is this cam on lifter bores. What compression ratio does this cam like. Engine is a 1915cc type1 for daily driving.

W-130
advertised duration 308º duration @ 0.050" of lift 267º
advertised lift at cam 0.419"

and yes, some have used the 1.25:1 rockers with that cam. Although it was designed to be used with stock rockers.

Engle lists the W130 as suitable for 1.1:1 or 1.25:1 rockers and I don't think it has a rep for wearing lifter bores.

A lot of duration for a daily driver, though. I once ran a W125 in a 1750 as a daily driver and was quite driveable ( 44 IDF's and well ported 40x35 heads and 1 1/2 merged exhaust).With the revs available it was a little hard on valve springs, if i recall.

What's the rest of the combo? Once it's running and you have some miles
on it please post again. I'd love to hear what you think of it and how it drives. Al

I was thinking weber 44idf, 40 x 37.5 valves in the head and 1.25 : 1 ratio rocker arm, compression 9.5 : 1, 1 5/8 bugpack headers, scat dragfast straight cut cam gear, muffler i am not sure what to get at this time but a dyno max would be nice. We have E10 and 90 octane gas here.

A 130 is a pretty agressive cam for a daily driver and for a smaller motor like yours. In a 2276 or 2332 it would work better. If you're intent on running that cam bush your lifter bores for sure. You may want to consider the FK-10 with 1.4:1 ratio rockers. 266 vs. 267 duration, 0.539 vs. 0.524 lift. It would be a lot easier on your valvetrain, especially for a DD. Were I you I would use a FK-8 or Web 86B. It would make for a more livable combo on the street and still have plenty of punch. 9.0 - 9.5:1 static would give you 6.8 - 7.0:1 dynamic CR, perfect for 90 octane gas.

I'm building a 2276cc and had planned on trying to get either a 120 or 125 cam, but found a 130 for sale cheap on craigslist so now I've got that.
The guy who sold it to me asked if I was building a drag bug or an altered gas racer and then looked at me like I was crazy when I said daily driver.

I'll be using the ACN Level 7 heads (42x37.5), a straight cut cam gear, and I have no idea yet what ratio rockers or crank, I still have to buy them..

Once I get it together and drive a few hundred miles I'll try and remember to come back to this thread with some more $0.02..

How is the dynamic CR worked out.

I run a W130 cam with stock rocker arms, P&P 40x35.5 044's, 9.5 to 1, dual 44 Webers, and 1 5/8 merged with mondo muffler on a 2332. It runs great. Very tame but opens right up when you wanna go. This is not my daily driver.

Use this and fill in the blanks, it'll calculate it for you:

You'll need the intake closing point from a cam card or call Engle.
