I need Engine

<< < (5/6) > >>

ricardo1967:
I filled my SBC 400 production block, 30 over. A lot of prep work to do it right (included muriatic acid etching in my case). Next time I'd just go with an aftermarket block, like Dart SHP, not filled. I like the idea of not HardBlok filling the coolant galleries, making the engine block as sort of a radiator.

gasserx:
Tile grout? Sounds like something i could test if i had several engines, but not sure if thats something i`ll do right now.

So an unfilled block is okey? Any more votes for that?

I would love to buy the best parts like a new aftermarket block, but i cant afford that at the moment. More important is to have an engine that works and to learn to get used to the car the first season.

To fill it or not basically depends on:
a. Thickness and integrity of cylinder walls.
b. You HP goals.

You could also opt to not fill it in your first season and do it later. I think having full water jackets adds some safety margin to bad tuning or abuse of running an uncooled engine for too long.

Entry level aftermarket blocks start at $1.5K, not as bad as they in the past. A fully race prepped factory block will not be too far from that.

gasserx:
We already have a stock 010 350 block, so we will use that. $1500 is better to spend on the other parts at the moment.
Not sure what to say about hp goals, but i think we can live with a 5-600hp engine as a starter? Im actually not sure - as i dont have anything to compare with. Never drove a dragster before  ::)
Fastest i have done on the 1/4 is a 13.5 sec with a 1953 floorpan beetle with somethig between 170-190hp. And that car was probably heavier than my FED.
I just want to learn, have fun and meet with other people with the same interests. Im only 36, so i hope i have plenty of time/years to build wilder stuff later on.
Might be worth to mention, is that we will possible not be able to make more than a maximum of 5-6 race weekends in a summer. Short season and few races within reasonable distance. In worst case we can end up with just a couple of weekends - rain is unfortunatly a huge partykiller over here.

George:
We ran a production 350 4 bolt block for several years. It made 650 dyno hp . We ran it dry and water filled. I preferred the block and heads water filled because I could preheat the engine with freeze plug heaters. The car weighted 1480 wet ,with driver and ran a best of 5.05 138 1/8 mile. I still have the complete short block .
