I am going to start collecting parts for my 383 build soon and want to get the right parts. These are what I am thinking... https://www.summitracing.com/parts/c...8/applications
https://www.summitracing.com/parts/sca-1-41829/all I am worried about piston slap with the valves as the pistons are dish shaped.

http://www.airflowresearch.com/195cc...cylinder-head/ Do I want the 65 cc or 75 cc combustion chamber?
As for injectors I was told #36 would be good. https://www.summitracing.com/parts/tfs-89036

As for roller rockers, pushrods, roller lifters, I have no clue what to get. Orr89RocZ I wish you lived in NorCal, I'd have you build my engine.

 

All looks good. Do the afr heads in 65 cc and get the spring up grade for 75$.

Ls7 lifters if oem block.

Tha setup will run good. Alittle lower compression than i like but good for atreet low oct gas

 

I'm going to go to PNP and find a 350 4 bolt block. As for pistons what do you recommend to get better compression? I want to go with forged. And rockers and pushrods?

 

If you trust your tuning i would go forged flat top for nearer 11:1 comp but tune on premium pump gas. Might need to keep it richer and lower on timing in spots but it should be doable

If thats a concern run flat tops with the 75 cc head chamber. That be 9.82:1

Or keep dish between 8-12 cc. 12 cc and 65 cc head would be 10.1:1. This is harder to find tho, most dish pistons are 16-28cc which means more like a boost piston.

 

Ok I found the LS7 lifters if these are the ones. https://www.summitracing.com/parts/nal-12499225
Thanks for your input. I'll be bugging you more once I get into this sometime next year. Oh by the way my last name is Orr

 

Cool! Those lifters are if you get the oem roller blocks. Any oldschool block wont work

 

I am going to get an 87 up 4 bolt block. I'm going to try to find one from '92-'93 years.
