Thank you!

I’m planning on purchasing a Magnum crankshaft from you and my engine builder says we need to have the crank checked for straightness after you ship it to us, he has all cranks he installs checked whether its your’s or another companies. What is your opinion on this?

Dave,

Hi Tech,

I am freshening my engine. It is a Steve Schmidt 618 BBC with your Pro I-Beam rods. The motor was built 8-10-2012 and in reading your rod bolts it looks like it’s either BLT160-CA or BLTC1735. They are 6.800 rods. Can you please tell me which rod bolts I need being that is was built in 2012. And can you sell me these rod bolts?

if you need any further information please don’t hesitate to email me.

Thank you so much,

Dave D

Hi Tech

I am in the process of building anLS3 for a boat and wish to stroke it to 410 cubes.

The engine will have a carburetor and the heads will be CNC ported and we want around 700 flwhp

The max rpm we are wanting to run to is 6750-7000 max

Can you recommend a rotating ass that will be reliable with the above in mind Thanks

Hello.I have BBC compstar 6.385 I-beams with ARP 2000-03 and 2000-04 on the rod bolts. I’m looking to replace them .Which bolts do you suggest ? Thanks,Kelly.

Kelly,

Please look on the end of the rod bolt & find the part # on the bolt head. We’re likely going to recommend part #BLTC170-L19 which is a Connecting Rod Bolt, E Head Style, L19 Alloy, 7/16 in. Diameter, 1.700 in. Underhead Length.

Please verify the P/N on your current rod bolts so we can be sure.

Thank you,

I have the U15270 rod kit that came with H11 bolts, but would like to use the aged 625 ARP bolts. Do you have the part number for this? or have the specs of the bolts that came with my rod set so I can ask ARP for the aged custom 625 bolt part number.

John,

The part # you can ask us OR ARP for is the Callies Part Number BLT-160.

Thank you!

What lube should I use on the rod bolts?

If they are Ultra Rods, use ARP Torque Lube (included in the box).

If they are Compstar rods, use #3 Extreme Pressure Lube (included in the box).

I’m building a 436 SBC probably going to start with around 750 to 850 HP. But will increase HP over time once I get used to the car. Going to run nitrous eventually also. recommendations for rotating assembly? I want it to be able to handle 1500 plus. Running PG, 5500 stall and 456 gear thanks!

Kevin,

We would recommend a Callies Magnum crank & Ultra I beam connecting rods for that build. If you’d like to give us a call at 419-435-2711 we could get the details worked out and put on your order.

Thank you,

I’m building a 436 SBC dart iron eagle block, AFR 23degree 230cc’s. 750 plus lift solid roller cam in a 75 camaro back half car. Power glide and 456 gears. Probably be around 750 to 850 HP to start but will add significant HP later. Recommendation for rotating assembly.. FYI I plan on adding nitrous thanks.

Thanks for the remmemdation didn’t realized you guys replied lol. I’ll definitely give y’all a call!

What is the HP rating for the Compstar bcc ultra I beam 6700 rods. I have a set a 8-10 years old with few runs may use them? Thank you

Sending you an email now.

Building a bbf 598 twin turbo motor. I noticed in you catalog that you have 6.7 and 6.8 length rods to be used with a 4.5 stroke and 4.600 bore. My question is do you offer or make a shorter rod to help get the compression down lower.

Hi Gary,

We are emailing you now.

I’m rebuilding my 540. It has a Magnum crank and ultra rods. I’m replacing the rod bolts for cheap insurance. ARP L19 bolts cpl-160. Do you recommend torquing the bolt a certain number of times or just use the stretch method? I’ve heard guys using both methods.

I have a set of compstar 6.535 bbc rods.what are the numbers on the big end of the rods on the side by cap parting line

Thank Mike

Hi Michael,

One of our techs will be emailing you shortly. Thanks!
