    Tfs Top End... Evolved???

    I forgot about the "billet" rockers and the badass valve covers that are needed. as always, if its a dog buy more parts rather than actually figure out what the problem is. ;) funny thing is ive run the kit on a car bolted on out of the box as per the owners request. 270rwhp and 8.20s @ 85 mph...

    Building A 331 Stroker.......advice

    my buddies stock '13 coyote went 8.20s@85 in the 1/8th. now with a tune and CIA its running 7.90s@89. a 331 with TFS heads and a real intake should easily go 7.20s on motor. there is a 331 combo running around here with a holley systemax 2 intake, afr 185s running 6.90s@95 on motor. with a...

    Tfs Top End... Evolved???

    im not a fan of the track heat intake, and I really don't like the street intake. both seem to lack what a port matched gt40/cobra will do, and neither of those are great intakes either. honestly, the heads wont matter with any of the above intakes OOTB. another problem with that kit is the...

    Tfs Top End... Evolved???

    a couple of years ago I did the kit that came with the stage 1 cam and the track heat intake on a buddies stock 302. it only made 270rwhp. I was less than impressed. ive seen more than that out of gt40y heads with a gt40 intake and an F cam. if it were mine, I would do a holley systemax 2 with a...

    408 stroker streetable??

    if he wanted to know the opinion of someone trying to sell the parts im under the impression he might have emailed or called you rather than post it on a forum and get opinions from those with nothing to gain. since you have a vested interest and stand to make $ off of this I wouldn't exactly...

    Has Anyone Ever Used Grade 5 Bolts As Head Bolts. Any Success?

    considering oreily has felpro 302 headbolts for $23, and Mr Gasket bolts for $32, I don't know why you would run hardware store stuff. my buddy has a set of pro comp head studs (against my advisement) on his 410 with 14:1 compression. I know people have had issues with those, but he has been...

    408 stroker streetable??

    since it appears a non sponsor is pushing their engine ill put in my $.02 since I have nothing to gain.: $6k is a little steep for an engine built from a $50 block that stops making power at 5k because the top end is restricted and is running a HR that would be better used in a 302. for the same...

    Wierd 5.0

    assuming your speedo is correct and a tire diameter a little under 26" and a .68 od its probably got a 4.56 in it.

    91 Mustang Gets Squirrelly After 50mph

    if it has the original control arms in it the bushing being rotted out of them could cause the car to rear steer and do this. you might want to put the car on jackstands and have a look under it. the noise could possibly be a torque box issue but there is no way to know until you look at it...

    Disappointing Times At The Track!!

    if you bogged it out of the hole that could be the reason the mph was low. you need to put a real tire on it and leave hard. the car should be able to easily run 1.8 second 60' times. when I was in high school my lx hatch with stock motor (including stock intake, tb and maf) with exhaust and...

    342 Afr 205 And I Need Help!!!!

    if its a nitrous converter it probably wont run on motor as well on motor. if you are going to run 1/8 mile on motor tell ptc that, send it in and let them do what they do. If you don't want to start with the other cam you have I would start with that comp solid roller I gave the pn for if the...

    342 Afr 205 And I Need Help!!!!

    I don't see any reason with the right cam and a change in converter it wouldn't run 6.60s-6.70s on motor and low 6s on the gas. my buddies high compression 347 went 6.40s at 105 on motor. a lot of this is in the converter. a 275 shot is a lot of nitrous.

    342 Afr 205 And I Need Help!!!!

    No. with the cam you have you don't need c16, let alone c23. and, you cant mix either those. once you change the cam to something more appropriate, if you are only gonna run about a 150 shot a mix of good 93 (like shell) and c12 will be fine. with a 300 shot pure c12 will be more than fine, and...

    mark at bullet cams is good. if you've got that other cam no reason not to try it first

    342 Afr 205 And I Need Help!!!!

    my buddies 347 with my rhs 215s and a little smaller cam than yours was still pulling at 8k rpm. if you want something off the shelf comp xr274r pn 35-770-8 would be a good choice. install it dot to dot.

    342 Afr 205 And I Need Help!!!!

    my buddies 347 with 14:1 compression and a similar cam that closed earlier only made 200 psi of cranking compression. at 10.7:1 and a 60* intake close event that thing is bleeding off a lot of cylinder pressure. if it were mine i would run a cam in the 230-240* duration range with a intake close...
