I am building a 351w speed density engine for my bronco. Maybe i should be but I am not looking to go MAF. Haveing asked some friends with experience on both sides (MAF/SD) i have narrowed it down to two flat tappet possibilites for my cam selection. The block will be bored 30 over (pistons to be decided) gt40 heads 1.6 roller rockers and an edelbrock performer intake. Now for the undecided part which cam to go with ? It has been recomended to use one of these ;http://www.summitracing.com/parts/cca-35-255-5

or http://www.summitracing.com/parts/crn-444232

Am i on track or is there a different choice. Please advise.

That's the cam I put in. I like it, it works well with my GT-40 heads and I still have a good idle. I recommend itLinkbar lifters can be used to retrofit a roller cam into an older block..."
