My good head is a C3AE 6090K. It would be great to match but at the end of the day I need a 63/64 head to get it back together. Thanks

Thanks Cody, I appreciate the feedback. I think I will be asking for a dominator for Christmas this year!

Looking for carb input on switching possibly from a 4150 carb to a dominator 4500 carb on drag car combination. Current engine is 498 ci FE with trick flow heads, 12.8:1 compression, custom Flat tappet cam 258/268 @ .050' with .649"/679" lift, trick flow track heat intake with 4150 1050cfm quick fuel carb running 110 octane race fuel. Car launches from transbrake at 3600-3800 rpm and crosses finish around 6,500 rpm. I do not have unlimited resourses so seeing if others have experience with a similar combination. Plan would be to just add an 4150to4500 adapter to current TF intake. Is anyone currently running a dominator on that intake with an adapter? any comparison info you can share? HP change and/or time slip changes? What size cfm dominator would be best? Thanks in advance for any help you maybe able to provide.

This year we put together a bigger engine and have been running into some issues not seen in prior 400 ci engine combinations.

498 ci engine with trick flow heads, 12.8:1 compression, custom Flat tappet cam 258/268 @ .050' with .649"/679" lift, trick flow track heat intake with 1050 quick fuel carb, 110 octane race fuel

Engine is ran in a rear engine dragster with powerglide and with driver is 1800lbs. First weekend out we struggled to get the car to go down the track fighting horrible tire shake, so bad it kicked the power off one pass. This past weekend we did find a tolerable tire pressure to get the car to go down the track with a best 1/8 mile time of 5.19 @ 128mph shifting at 6,300 rpm. Engine seems to be running very strong but would like to get input on the two timing/fuel questions below. It would be great to have a test day to get 6-8 passes to test variables but it seems most tracks barely give you 1-2 test passes so looking for the groups help to dial in the combination so we can get back to racing and winning!

1. Current timing is at 34 degrees and that is what our old smaller FE engine seemed to like but not sure if that is the right number for this bigger ci engine?

2. Spark plugs we are running are AR3910. The procelain on all plugs seems to be yellow. We have tried adding fuel but only seems to slow car down so assume it is on rich side but not sure what is causing the yellow color or what the cure would be?

Thank you in advance for any help you are able to provide!

Thanks!

In a drag race application it picked up nearly a tenth in 8th mile over an aluminum dual plane. Also ports matched up almost perfect to stock heads all we had to do was bolt it on.

Sorry in advance if this has already been covered but could not find searching. Does anyone have int/exh flow numbers for stock ford high riser heads? looking into a couple different combinations and would like to have a flow to compare. Thanks in advance

Prior to 2018, I had been running a 1964 Galaxie with a 445 FE in it running 11.50 in the 1/4. I always wanted to go faster but at 4,000lbs with driver we would always fight the weight. So, the Dragster was bought used rolling in fall of 2017. That winter we converted it from BBC to FORD FE powered. It took us engineering a few custom made parts and most of the winter to get it together. We chose to use our back-up engine as the break-in mule given we had a "new to dragster" driver and a uncommon combination. The Back-up engine was a 390 Ford FE, stock crank, trw pistons, .602 lift flat tappet cam, stock C4AE heads and a ford dual plane aluminum intake. Best pass first weekend out was 6.12 @111mph. We continued to adjust shift point, tire pressure, carb spacers and after a few weeks had it running around 5.95. Mid 2018, I installed the new trick flow single plane intake and picked up nearly a tenth. Best pass of 2018 was 5.82 @ 116 in optimal conditions. Over this past winter we decided that the dragster would be a perfect platform to gauge the impact of the new Trick flow heads. So over the winter we installed a new set of trick flow heads. Only change we had to made was to mill the rocker stands .200. Everything else stayed constant and our best pass to date is shown below. Our intention originally was to switch to a larger cubic inch motor year 2 but its been fun trying to see what we can squeeze out of our 390 test engine. Plus, in a sea of BBC dragsters its always fun to see people double take that it is in fact a ford, which in itself is odd in a dragster, but also an 390 FE!
