Stu5766 394 Posted June 1, 2017 Evening people. I'm just in he process of upgrading to a solid camshaft. Have decided to go with a Crane F246. Its a 351 30 thou over with 4MA Crank, closed camber 2v's with port work. Roller rockers, airgap manifold with 750HP DP. MSD dizzy, 4 into 1 pace makers with twin 2.5 system. Also I have calculated the comp ratio & its 10.6 : 1. Whats people's experience dailing in this cam & what kind of HP would I expect from it? Cheers stu. 2 MNTL.XD and Valvebouncer reacted to this Share this post Link to post Share on other sites
MNTL.XD 3,831 Posted June 2, 2017 Subscribed, i'd be interested to know myself, very similar (pretty much identical) combo to mine. What cam were you running previously and what power did it make?Sent from my SM-G900I using Tapatalk Share this post Link to post Share on other sites

I've just had 25thou taken off of the heads. It was good for a 13.3 1/4 mile pass with a top loader & 3.9 LSD 9". I'm hoping to exceed 300rwhp & drop it into the 12's. 2 MNTL.XD and gerg reacted to this Share this post Link to post Share on other sites
gerg 10,871 Posted June 2, 2017 Mate there are quite a few more hydraulic ones above the one you have before needing to go solid, but if you must go with solid, so be it I guess solids have a much more aggressive opening than hydraulics, so comparing apples and oranges. 1 Thom reacted to this Share this post Link to post Share on other sites

The Crane F246 seems to have proven itself as a good performer in various applications. My engine has the adjustable rockers, guide plates, & valve springs setup. The F246 also sounds cranky as with a set of iron heads. 2 gerg and Valvebouncer reacted to this Share this post Link to post Share on other sites
MNTL.XD 3,831 Posted June 2, 2017 I love the sound of solids. Gives me a little stiffy. Sent from my SM-G900I using Tapatalk 3 Thom, Stu5766 and Valvebouncer reacted to this Share this post Link to post Share on other sites
Thom 6,650 Posted June 2, 2017 Solids are cool as a kelvinator, but more work than a hydraulic 2 Stu5766 and MNTL.XD reacted to this Share this post Link to post Share on other sites
blu xe 825 Posted June 4, 2017 F246 has been the basic go to all rounder for years with clevos. Was a very popular cam to use in the 90's for a tuff street clevo. Many were 12 second cars with pretty good drivability. With the better manifolds and heads available these days you could screw some decent power out of that same cam these days. In saying that theres probably many more grinds that would work better than that cam as well now. 2 MNTL.XD and Stu5766 reacted to this Share this post Link to post Share on other sites

It's an old school car with iron heads, so should be happy with the cranky sound it makes & will be more than happy if I get it into the 12's. 2 gerg and blu xe reacted to this Share this post Link to post Share on other sites
Stu5766 394 Posted June 6, 2017 Well I had some progress this arvo. I degreed the cam & it was within .5 of a degree straight up at dot to dot. I would up fitting the 40 thou style steel "O" ring style head gaskets, so comp will be a tad higher than expected. The contact point of the roller on the tip of the valve stem is near on dead in the middle. 2 MNTL.XD and bear351c reacted to this Share this post Link to post Share on other sites
