would this block and roller conversion work together.....i am wanting to use all trickflow top end stuff

[Iwannagofast]

also do you guys think it would be worth it to buy that block or find a used one localy.....i think i could get a 351 whole bottom end for around 300

What year 351 bottom end can you get

[ryans88gt]

No they will not work together unless you use a small base circle retrofit roller cam.

You basically have 4 options for a roller 351w.

1) Solid roller cam and solid rollers work with any 351w block

2) 94 and newer F4 blocks, which accept 5.0 style roller lifters and cams, but the blocks are slightly less strong with lower nickel content and not as thick main webbing, but still stronger than an A4 302 block.

3) 93 and older block with standard cam and retro fit roller lifters with link bar (cost about $500 for the lifters which is the down side here).

4) 93 and older block with a retro fit small base circle cam, stock 5.0 lifters, and the stock 5.0 dog bone and spider locating system.
This is cheapest, but the downside is you have a limited number of cams to choose from although you can always get a custom comp cam or something and some people say that the small base circle cams are not designed for higher rpm and wear out components faster, while others say they are fine.

Here, I just saved you thousands of dollars and some head aches...your welcome. You can get this setup with a 94 and newer block or the 93 and older. Call them and talk to them, they have been building engines for a long time and know what they are talking about.

thanx a lot ryans88gt

[Iwannagofast]

that is an awesome set up for the price......you werent kidding when you saved me thousands.......the only way i would think it could be better is being 4 bolt main......so could i use the trickflow roller cam with that or should i just do flat tappet

[Speedstang302]

if you can do the roller def..do it..solid or roller are WAY better than flat teppet

[Iwannagofast]

yeah i definately wanna do roller.....I like the idea of the trickflow kit since all the parts are made to work together well.....im hoping for around 500 horsepower at the flywheel with the 408 and trickflow top end with all supporting modds

I don't mean to argue, but a 347 making 500 hp is not that easy and really will not cost less, and will definitely not last as long as a 408.

500 hp should be a reasonable goal without getting too crazy with the 408. If you ask for a 94 and newer roller block you will be able to use your stock roller components. I would probably get the trickflow R topend kit for a 408, they need a lot more air.

BTW, they will throw a main girdle and studs on there for an extra $150.

well i know 500hp is kinda hard but no real difference between 460/470hp and 500..and he wants to use trick flow top end on this 351 thats not cheap..and yeah 408 would last a little longer..but you cant say that it depends on driver!!!

[ryans88gt]

Sure, it depends on the driver, I mean you could always shift it into 1st gear at the end of the track and turn 9000 rpms ...lol

but a 302 with 347 has a higher sidewall load than a 351w with a 408. In general 351w block can handle about 700-800 hp. A 500 hp 302 is living on borrowed time, a 600+ hp stock block 302 is like a dead man walking.

I thot that 500 hp would be pushing that 347 to about its limits....plus i wanna have the option of maybe adding a lil juice or a couple lb.s of boost on down the road if i wanted to.

And the part about the 94 block?....all i got do is ask for that type of block and they will build that same setup with it instead so i can do roller cam and lifters?

this is helping me a lot

500hp is the limit of the stock block stroked or not...but the dart, world or boss 302 blocks can handle bout same as stock 351w blocks..!!!

[Iwannagofast]

i have no doubt about that its just that those blocks cost as must as that entire 408 bottom end

um if the bottom end was gold plated...my CHP 347 stroker i had quoted (not built yet) was $2100..the bottom end iz like $800..so 408 shouldnt be much higher!!! and a dart block is like 2900...and the boss i think is more than that!!!
