Where should I install this cam?
In the engine would probably be the best place
Seriously though…
351w +.030”, .005” deck with 12cc 4vr flat tops, ported 69cc smogger heads with 1.78/1.45 valves. 8.75 to 9.0 compression depending on what head gaskets I use. Gave up waiting in the cam I was going to use (it’s been over 3 months) and will instead use a stock ‘89 mustang 5.0 hydraulic roller cam. It is 276/266 sae seat duration (reverse split), 214/211@.050, .444/.444 lift, 115.5 lsa/115 ica. This is the later revised version mustang cam with the gentler intake lobe. Heads flow 176/151 (w/pipe)@.400” lift and only gain 1-2 cfm every .100” above that. It will have 1 1/2” long tube headers and a stock or performer dual plane intake. Daily driver type usage in a 4400-4500 pound truck with 3.55’s and a stock converter C-6. Would like to use 87-89 octane fuel.
Debating on using a +4, +6, or +8 advance on the cam. +4 puts it at a 111 ica, which seems late for a low compression engine. +8 puts it at a 107 ica which seems more appropriate, but that also puts the exhaust opening very early. I’m only worried about the idle-4500 rpm range, with the primary operating range being 2000-3500 rpms.

Re: Where should I install this cam?
Degree it and see where it's at first.. Year's ago a guy that had a 5.0 mustang with high mileage used to race every week at the track .It ran low 13s then he had a front cover leak and when he fixed it the timing chain was very loose so he replaced it and the car lost 4 tenths.

Re: Where should I install this cam?
Are you debating this based on your degree readings or just throwing it up in the air and hoping based on the cam card?travis wrote: ↑Mon Jul 12, 2021 1:47 am Debating on using a +4, +6, or +8 advance on the cam. +4 puts it at a 111 ica, which seems late for a low compression engine. +8 puts it at a 107 ica which seems more appropriate, but that also puts the exhaust opening very early.

Hot tip, go through the big hole in the back and no one will see it and copy the secretMark O'Neal wrote: ↑Thu Jul 15, 2021 3:22 am I'd go through the big hole in the front of the block.....

Checked with a degree wheel. There is no cam card as it was pulled out of a running engineDave Koehler wrote: ↑Thu Jul 15, 2021 10:03 amAre you debating this based on your degree readings or just throwing it up in the air and hoping based on the cam card?travis wrote: ↑Mon Jul 12, 2021 1:47 am Debating on using a +4, +6, or +8 advance on the cam. +4 puts it at a 111 ica, which seems late for a low compression engine. +8 puts it at a 107 ica which seems more appropriate, but that also puts the exhaust opening very early.

Re: Where should I install this cam?
You could install it on ebay to fund getting the cam you want for that build.
Re: Where should I install this cam?
Typical 115 lsa cams often get a good result (for more low mid torque )by advancing 7 degrees.
108/123 centers based on .050" events.
Mild decrease in top end you probabily don't need.

Re: Where should I install this cam?
My question is, what was the cam you were waiting for?
Looking in an old Clevite engine parts catalog, their specs for the 1989 302HO replacement cam are a little different than what you found.
Part number 229-1774, “SAE” duration 297/279(might be typo?), 210/210@.050, .278/.278 lobe lift, 116ICL/115ECL.

Somewhat handy with a die grinder.

Isky 262h. The expected delivery date just keeps moving out farther and farther.PRH wrote: ↑Thu Jul 15, 2021 4:31 pm My question is, what was the cam you were waiting for?

Ford lists this cam as 276/266 on a 116 lsa. I’ll remeasure it at .006” lifter rise because I can’t remember what I got last time I measured it
Re: Where should I install this cam?
The SAE spec is .006 lift....... at the valve.
So, theoretically.00375 tappet lift for a 1.6 RR.
I’m not really a Ford guy at all, but from what I gathered while digging around, the earlier version of the HO cam was supposedly “266/266”, and made a little more power with it’s faster intake lobe.

FWIW, Amazon shows a Comp 252h as being available with 8 on hand.
Comp 35-215-3

That's Funny Right There... I Don't Care Who You Are.
Here is a 118 LSA advanced 12 degrees in a 357 ci SBC, you will notice that tq sucks but HP keeps increasing.

Most install gains I have seen require dyno time because they are usually in the 3 to 5 HP range and can depend on where you need that modest gain.
