Weird lift split.

No guts below 4500 RPMs. Hope you have good rod bolts.

 

arp 2000

 

so a long rod 427 with some bore, why not use the 4 inch arm for some more torque? 11 to 1 compression, I assume its gonna be a street beater and torque is king. Super victor is also gonna kill alot of torque, I would use a victor R, or the new wieand team g if using a single plane but lloking at your combo I`m thinking if it were me I`d be doing a dual plane intake...how much does the car weigh, what gear and what tire size, that would help paint the picture a bit more..application as well, street??

 

it is just a car i take to the track 1-2 times a month nothing more it weights about 3500 with me in it 275/50/50 mt drag radial

 

430ci - short stroke w/ a very long rod, going to have an overly long dwell time, thus making it very octane & timing sensitive. The smaller heads & cam will help some in maintaining low-end torque.

I don't run over a 6.385 rod with under a 4" stroke, and we do a lot of short stroke combos.

 

i have a 1988 rs but i took out the v6 and put in a 454 bbc and a 4 core and that has 3 fans on it two 15's and a 12" and it still over heats i have changed out the thermostat to a 160degree from a 195 dagree and im running 97 octine and it still over heats only after 4 miles .... how can i get it to cool down to 200 i need some help on this .....

 

^^is the air dam in place?

what's the combo look like? lots of compression? etc?

 

Copper rad or alum? A 4-row copper won't do what a stock 2-row alum does.

 

copper rad and 4 core and the air dam is in place and its has lots of compression

 

go to aluminum rad, 4 core. aluminum dissipates heat better than copper

 

My 15:1 motor could be left running on the jegs 2-row aluminum w/ a CSI electric wp & single 16" elec fan and never see over 180*.

As Matt noted, put a decent aluminum radiator in and go from there. Copper is considerably less efficient than aluminum; I had a four row copper that wouldn't keep up with my 11:1 street small block.

 

just did a 4 core aluminum with two 15" ad one 12" lewts see how it deals
