Will this cam work good on my TPI

Im building my 350 tpi project and it's time to buy the cam. I'm using iron heads with 2.02/1.60 valves and match porting. I have a MAF intake also with lower intake match porting. I also plan on custom programming. I want a good cam with lots of bottom end but am shooting for under $150 bucks. I found this cam for 140 on ebay. Do you guys think this stick will suit this engine well? Any suggestions? All comments are greatly appreciated. Thanks for the help boys. Third gen Pride!

You do not want any cam for TPI with less than 112 LSA.

Is that the comp xe262hr? Well it has the advertised duration of a 262, I forget how the roller cams work like that. 260Hr?

The computer doesn't like overlap, 114LSA will make it run best. 112 will work. 110 is pushing the limits. That's why the "computer compatible" cams have 114 LSA's.

That cam is also available in 112*. Will this give me good street performance and a good exhaust note? It's actually an LT1/LT4 cam but it will work work in all 87 up aside of the dowel pin right?

Not a comp cams stick.

I have a 110 LSA. It may not be ideal but I haven't had any issues with it.
