Hey guys I am very new to the gen3/4 small block scene. i run a dirt late model and want to try an experimental engine. I would like to try a 5.3-6.0 in mycar. I have never seen one and have some questions. I will layout some specs / rules and go from there.

1. cast iron block and heads

2. manual / belt driven fuel pump

3 cubes limited to 362 max (I might fudge a little LOL)

4. Headers?

5. 450+ hp

a Lq4 or Lq9 is 364 CI, and its real easy to get 450 plus out of those with the proper heads/cam.

All I have found are aluminum heads our sanctioning body wont let our division run aluminium heads. the next step up can run all aluminium but they are super high dollar from Gaerte and Cornette and the likes.

im sorry man but the days of cast block cast heads is D-E-D dead. from what i know all 5.3 5.7 6.0s have aluminum heads.

yup, thats what I thought as well. Sounds like you are going to have to go old school SBC

I heard some of the 99-00 6.0 came with cast iron heads , I just cant find any casting #s the blocks are easy to come by. I found some on E bay but are they as good as the aluminium castings if they are worked on?

the only gen 3 iron heads are on the 99/00 6.0s. and i dont know what you would do about a manual fuel pump.

the fuel pump is easy it will mount on the bellhousing and be belt driven off the drive flange for the trans input shaft. We dont have a clutch so its a combo power steering/ fuel/ oil if you run a dry sump.
