Miniram Question.
Any input on a good cam choice...Im putting together a 383 and I dicided to go with the Miniram to replace the TPI (85vette).
Im going to port and polish the stock heads, use the stock 48mm TB and 30lb injectors, 3:73 gear ratio, no cat, 40s Flowmaster, new chip.
Comp cams, TPIS, lPE??! what lift and duration...lobe etc...
Thanks

Theres a few guys on here that used the Miniram so Ill let them answer your questions with better advise...that being said,are you sure you want to use the stock 85 Iron heads,even with a port and polish?
Or do you have someone who can port them out and make them flow really well?I cant recall the last time I seen anyone using them heads ported out making nice power numbers.Just asking if youre sure you want to go this route.

Okay guys thx for the info..Its and auto, and money is an issue lol.
TPIS told me not to bother with 30lb injectors unless i upgrade the ECU with a DFI? Anyone use this? This fairly easy to install on a 85 vette?
I think ill go ahead and get new heads then
just might set me back another month er 2, unless I find a really good deal. Ill shoot for the 195's.

So im looking at 400+hp...will the stock ECU be able to handle this if I can find someone to tune it? I really dont want to spend 1k on computer stuff. JAKE...you ported these before?

I bought Edelbrock Performer heads for my '85 and theres a big difference in power and thats all I changed at the time. They're aluminum and can be ported to flow as much as AFR heads. My set with new ARP bolts cost about $1200. The AFR's will run you close to $2000.
Why only a .275 lift? Thats not much higher than stock.

A DFI setup is not required, that part is incorrect. A custom chip is required.
Ask your chip maker what size injectors you should run, they will be the one calibrating it. Some may recommend 24, some might go as big as 30. So ask them.

I don't think you can get Edlebrock heads to flow as well as the AFR heads. If you could get it to flow those numbers (286 CFM); providing there's enough material; they would probably be "hogged out" so big it would affect low and mid-range power. AFR 195 CC heads will support 600 HP, and cost $1450-1500 in ads I've seen.

check out these Dart Iron eagle heads 200cc...seems like for the price they flow just as good as AFR 195's? Half the price...am I missing something other than them being alum? http://www.dartheads.com/manager/upl...IRON%20SBC.pdf
