Im going to build my truck engine for my 454SS truck 1990.
Im building a gen VI 7.4 engine with vortec heads. Edelbrock TBI intake and modified trottle body, chip etc.
Edelbrock offer a`TBI frendly cam 218,228-.500.500. As what i have bin told, the TBI likes a lot of vaccum?. That means the cam need large LSA?.Right? What Roller cam will mach the flat tappet Edelbrock cam, or maby be better for what i am doing??

What is that you plan on using the truck for?

That is pretty much what I did on my 454SS. I used a Summit cam which was a copy of the Edelbrock. I used a RPM Air Gap manifold with a home made adapter. I had a Hypertec chip in it but it was for the factory setup. Still, it was pretty peppy. My neighbor & I would hook up most mornings on our way to work. He had a Honda CBR600 rice rocket that I could pull up to about 100 before he re-jetted it.

I want to use it on streets in the week ends. I donīt use it for towing. I look for as much power i can get with TBI. Looking for aīrollercam as im using gen VI 454 long block.

That Edelbrock cam works pretty nice even though it is a flat tappet.
I used to post here quite a bit back in the day. Lots of info.
