Bought my first c10, but have one question.

So as the title states, I bought my first c10. I am still learning the whole gas world being that I was really involved in diesels at one point (more specifically the cummins engine 5.9 era). When I got this truck I new it was a gem, and got a great deal from a great friend. This truck as a 92-93 454 fuel injected big block in it, more specifically it is TBI injected.

My question is, what is this engine capable of withstanding on the inside? Are the rods and pistons decent? crank? etc etc. Just don't know enough about this engine just yet and when I google it I can't really find a whole lot. Any pointers or words of wisdom would be totally great. If it helps I was wanting to make around 400-500hp and leave it at that. Hopefully by that time the sickness will not have started and I start dumping a crap ton of money into it lol.

Thank you guys in advance, I really appreaciate it! Below is a pic of the rig.

Re: Bought my first c10, but have one question.

What you have is rated at about 230hp/380tq.

There's plenty of talk online about how to bring those numbers up at many budget levels. Here's one on this site:

I think the consensus though is heads, cam and intake. I would go with a set of original oval cast iron heads and a mild RV cam while keeping your TBI setup.

Re: Bought my first c10, but have one question.

How is the low end in these motors? Well the crank hold up, I know you mentioned pistons but what about the rods? Are those pretty good too?

Thanks for the timely response by the way, much appreciated man!

I'll defer to those with more knowledge for definite internal component happiness with your goals in mind, but... 500hp out of a 454 is not a lofty goal and if you keep the RPM range under 6000, my guess is that the stock internals should not have any trouble with that!

Re: Bought my first c10, but have one question.

The Pistons in those engines are cast, but still good for that kind of power range. They have good forged rods, that are also plenty for that kind of power.
As others have said, the heads, cam, intake are the bottle neck. The heads and cam are the worse. I've seen a truck with the stock intake and TB still make very good power when the heads and cam is upgraded.
